The 2018 Jackson Generals entered the postseason with the fewest wins after the All-Star Break of any playoff-bound team. First-year manager Shelley Duncan had a message ahead of the North Division Series: “Get three runs.” Eight times in nine playoff games, the Generals scored three or more, winning six of those games. Stirred by two hot-swinging prospects and a strong bullpen, Jackson toppled the Montgomery Biscuits and Biloxi Shuckers for their first Southern League title as an Arizona Diamondbacks affiliate.

*Can the Generals score enough? – – Jackson averaged less than three runs per game in August, their lowest monthly total in 2018. They have to get production from bats other than Marty Herum’s (.361 BA in August) and Kevin Medrano’s (.310 BA in August), and they must be able to stay afloat against left-handed pitching. Jackson’s batting average against southpaws (.248) is 19 points worse than their mark against righties, and it’s generally harder to steal bases against left-handers as well, making Travis Ott and Brock Burke two of the foremost threats to the Generals’ playoff lives.


*Prospect pitching will be a critical balancing point. – – Though the rotations aren’t set, you’d have to imagine that Jackson will turn to No. 3 Arizona prospect Taylor Widener and No. 1 prospect Jon Duplantier in at least two of their first three North Division Series games. Recently, Widener and Duplantier have not been as effective as usual: In their past 18 1/3 innings pitched combined, they have struck out 28 batters (13.7 K/9) while also allowing 11 earned runs (5.40 ERA).  In a winner-take-all series, a short start by either one could put a heavy tax on a Generals bullpen that has been fantastic over the last month. Closers Yoan Lopez (0.63 ERA in August) and Kevin Ginkel (0.00 ERA in August) have been lights-out good, but Lopez, Arizona’s No. 18 prospect, was called up today to help out a Diamondbacks bullpen that allowed two late leads to slip away over the weekend in Los Angeles. The departure of Lopez leaves an important three-out hole in the late-inning plans for Jackson, one that manager Shelley Duncan and pitching coach Doug Drabek will have to creatively fill.


*Don’t procrastinate – win early, at home. – – This might be the strangest statistic in the Southern League this year: of the four playoff teams (Jackson, Montgomery, Biloxi, and Pensacola), the Montgomery Biscuits are the only squad with a sub-.500 home record (34-36). They’ve gone 18-17 at home in the Second Half, but the Biscuits’ offense somehow hits a head-scratching 41 points lower at Riverwalk Stadium (.236 BA) than at all the other parks in the league combined (.277 BA). Their ERA is also 19 points higher at home, meaning the Generals’ best chance to win the series is to force Montgomery into 2-0 hole before the series pivots to Alabama’s capital city on Friday. The Biscuits have won three consecutive games in their home ballpark only once this season, though it did happen within the last two weeks (against Tennessee, 8/24-8/26). “Hold serve at home” is one of the oldest maxims in coaching, but in this particular case, it’s exceedingly against the odds that the Generals lose three games in a row at Montgomery if they take the first two.


We should clarify a point of confusion here: the five-game series that Jackson dropped to Montgomery in late July/early August was not played as the statistics would have you believe. On paper, it appears that Jackson lost the series by losing the final three games at Riverwalk Stadium. In reality, the fifth game was suspended in a 0-0 second inning tie due to weather on August 1, and it was completed two weeks later at…yes, you guessed it, The Ballpark at Jackson. Playing the final eight innings of the series on the road, the Biscuits beat the Generals 4-0 to take the set. If the Generals can put the Biscuits away in West Tennessee at least once, they make the path to a Southern League Championship Series berth significantly easier to achieve. (Listen: if you wanted rocket science, you skipped over the Discovery Channel a few clicks back.)

Chasing Zeke: Kevin Medrano nearing Ezequiel Carrera’s single-season batting average record

Kevin Medrano (credit: Pam Dietz)

Kevin Medrano and Juniel Querecuto were two of the most frustrating players for opposing pitchers in the First Half. Between them, they cracked exactly three home runs (all by Medrano), and yet they hit safely more than 35% of the time. Querecuto did it with a lot of line drives, and Medrano did it with good bat control and tenacity, fighting off pitch after pitch before finally getting a single or even a double down the line. Before being promoted to Triple-A Reno, Medrano led the league with 24 doubles in the First Half, and his .368 batting average batting average before the All-Star Break was tops in the circuit as well. The question that nobody could answer was this: would it hold up?

The Generals’ all-time record for a season-long batting average is .337, accomplished in 97 games by Ezequiel Carrera back in 2009. Carrera’s feat helped the 22-year-old climb the ladder to the big leagues, where he would debut in 2011 with the Cleveland Indians at age 24. 508 MLB games later, Carrera owns a career .262 batting average in The Show, playing most recently with Toronto in the 2017 campaign.

Medrano’s record chase is happening in his age-28 season, perhaps too late to springboard him onto a big-league radar the way it did for Carrera. (Medrano has shown increased versatility on defense this year, playing both corner outfield spots and every position in the infield.) That being said, to take down the franchise record would be a pretty cool way for the veteran to make his mark. He’s batting under .300 in the Second Half, so a surge in production would benefit both his cause and the team’s championship chase. With less than a week to go, the finish line is in sight.

Marty Herum’s Southern League-best 19-game hit streak came just in time

With less than 15 games to go in the Southern League’s regular season, Shelley Duncan and the Jackson Generals have accomplished a lot, but they still have bigger goals in mind. This is part three of a late-season look at the Generals’ personnel and the battlefield ahead.


Generals third baseman Marty Herum hurt himself on the basepaths on April 24th, and the subsequent DL stint lasted more than two months. When he returned, the sixth-year pro had a tough time getting traction, batting just .202 between June 28 and July 27. But Herum, an undrafted signee out of the University of Wisconsin at Whitewater, kept on paddling. You don’t get to Double-A from the NCAA’s Division III ranks without running a few rapids.

Herum went 2-for-3 in the Generals’ July 28 win at Montgomery, and he added another hit the next night. And the next night. And the night after that. The hits kept coming, singles and doubles against the Biscuits, the Tennessee Smokies, and the Chattanooga Lookouts. The former Wisconsin-Whitewater Warhawk got two more hits in the August 14 opener against Montgomery against home, tying teammate Ben DeLuzio for the team-high streak in 2018 at 14 straight games.

Entering August 15, a challenge faced Herum: The Generals were playing a double-header, and an added wrinkle would make it even tougher to continue the streak. First off, game two of the double-header was set be a seven-inning contest, meaning Herum wasn’t certain to get a third at-bat. Furthermore, the first “game” of the twin-bill was the resumption of a suspended game (from August 1) in the second inning, and Herum had already batted once in that contest without getting a hit. Because the statistics from the August 1 contest had not yet been finalized, a hitless performance through the rest of the resumed game would undo part of the streak. Like an evil baseball version of Chutes and Ladders, Herum’s hot-hitting span would be reduced to separate four-game and ten-game streaks in the scorebook. Herum had to hit safely in both contests in order to stay near the top of the league leaderboard.

When the suspended game was resumed, Herum, came to bat in the fourth inning with two outs, a man on first, and the game scoreless. Marty singled through the left side to keep the inning afloat, officially breaking the tie with DeLuzio and matching Birmingham’s Eloy Jimenez and Luis Alexander Basabe for the longest streak in the Southern League this season. The Generals ended up falling 4-0 to the Biscuits, and manager Shelley Duncan slotted Herum into the lineup in the fifth slot for game two, meaning Herum was only guaranteed two plate appearances to try and top all Southern League competitors in 2018.

In the nightcap, Herum led off the top of the second inning in a scoreless game.

On the second pitch from Montgomery’s Sam McWilliams, Herum helped himself to belt-high fastball, breaking the 0-0 tie with an opposite field home run over the 16-foot wall in right. The dinger was the 26-year-old’s first in almost four months, and it spurred Jackson to 5-1 victory while extending his hitting streak to a league-best 16 games.

Herum’s streak ended at 19 straight contests with a base hit. It’s the longest hitting streak in the Southern League since Jacksonville’s J.T. Riddle hit safely in 25 straight games in 2016. Part of the fun of Herum’s success has been the coverage of Herum’s streak by the fan-run Twitter account, @HowsMartyDoing. With 366 followers, the audience may be small at present, but the laughs run big. At any rate, it was awesome to see Herum find a groove in the latter part of the Second Half. Marty is batting over .300 in August, and his stick will be a critical component for Jackson if they want to succeed in the playoffs.

Ben DeLuzio catches everything. Can he catch Corey Ray in the Stolen Base Race?

With less than 15 games to go in the Southern League’s 2018 regular season, Shelley Duncan and the Jackson Generals have accomplished a lot, but they still have bigger goals in mind. This is part three of a late-season look at the Generals’ personnel and the battlefield ahead. 


It’s not hard to see the difference that Ben DeLuzio makes when he’s healthy. After hitting a scorching .355 in July with 15 steals, he went back on the DL with a busted lip that required stiches after on a headfirst slide into third base at Chattanooga. (Spoiler alert: he stole the base, No. 25 on the year.) Upon his return to the roster a week later, DeLuzio set about catching everything that threatened the outfield grass, totaling 10 putouts over August 17 and 18 to lead all Jackson and Montgomery players who were not catchers or first basemen. Nearly every one of DeLuzio’s grabs involved a dive towards the infield, a calculated angled into the gaps, or an on-your-horse sprint to the center field wall. Montgomery managed only 3 runs over their final 19 hits in those two games, losing both contests as the Generals beat the Biscuits in a series for the first time in four tries.

On the basepaths, DeLuzio collected 27 stolen bases in 58 games through August 23, trailing only Biloxi’s Corey Ray, the league leader at 33 (through 124 games). Ray has swiped one base in August so far; DeLuzio has taken three. Ray is vying to become the first Southern League player in modern history to lead the circuit in both home runs and steals. DeLuzio might be just the man to spoil the fun. There’s a photo of the superhero Wolverine on DeLuzio’s locker, taped there in jest by a clubhouse prankster who thought DeLuzio’s beard and intensity resembled the character’s. There’s still time, and patience, as the saying goes, is not Wolverine’s strong suit. If there’s a series to target, it’s the matchup between Jackson and Birmingham at Regions Field (August 24-28). Birmingham catcher Zack Collins has allowed 19 stolen bases to the Generals this year, more than any other catcher in the league. Even with a revamped Barons rotation, DeLuzio should be on the move.

Taylor Widener Is The Best Starter In The Southern League, And Other Pitching Notes

With less than 15 games to go in the Southern League’s regular season, Shelley Duncan and the Jackson Generals have accomplished a lot, but they still have bigger goals in mind. This is part one of a late-season look at the Generals’ personnel and the battlefield ahead.


Baseball America recently released their annual “Best Tools” survey that took votes from league managers to determine which players had stood out by individual skill. Ben DeLuzio (Fastest Baserunner), Shelley Duncan (Best Manager Prospect), and former General Wei-Chieh Huang (Best Changeup) all represented the Jackson squad in the voting, but one name was most notably absent: Taylor Widener. The 23-year-old right hander escaped any noteworthy vote totals for Best Fastball (Dylan Cease, Birmingham), Best Breaking Ball (Kyle Wright, Mississippi), Best Control (Duncan Robinson, Tennessee), and Best Pitching Prospect (Griffin Canning, Mobile). Those votes may be legitimate, but at some point, you have to explain the thorough fashion by which Taylor Widener has dominated his peers in the Southern League.

Status Update 7/11/18: Stupid, Splendid, and Specious Splits (Pt. 2) – Generals Hitters

Rudy Flores - Sewell
Splits won’t tell you a lot about Rudy Flores that you can’t observe on your own. Guy can swing it. (Photo credit: John Sewell)

NOTE: This is the second post in a two-part examination of split and component stats. Check out our pitching-focused post from yesterday

JACKSON, TENN.One of the more fascinating things about the game of baseball is the way certain component numbers deviate from one another when breaking down overall statistics. Some guys are great in day games, while others play better at night. Why is that, and who knows it? There are certainly answers for some of these oddities, but do they all matter? It depends on whom you ask. Let’s take a look at a few of the interesting season splits for the Generals, through 7/8/18:


HITTERS Home/Road Day/Night 2 Outs Ahead/Behind in Count Bases Empty/Men On
Cribbs .374/.329 .267/.223 .318 .489/.173 .324/.378
DeLuzio .286/.276 .229/.308 .250 .410/.108 .284/.283
Flores .409/.352 .383/.380 .333 .532/.283 .347/.410
Herum .348/.347 .320/.296 .293 .488/.200  .353/.344
Leyba .306/.347 .346/.326 .333 .492/.216 .390/.271
Littlewood .302/.323 .304/.316 .346 .507/.073 .321/.308
Prince .407/.374 .407/.387 .365 .575/.173 .411/.368
Robertson .346/.376 .382/.359 .448 .488/.255 .359/.367
Rosario .382/.219 .176/.357 .429 .423/.176 .353/.302
Vinicio .287/.272 .222/.294 .329 .382/.261 .267/.294
Westbrook .294/.363 .177/.309 .323 .411/.291 .341/.315

For the record, DL players, players who joined the team in July, and players with fewer than 20 games played at Jackson aren’t on this list.

*Spoiler alert: Rudy Flores can get on base. Good hitters can get on base under almost any conditions, and Flores shows you that by consistently getting high marks across the board in the above categories. There’s a reason why he’s a two-time Southern League All-Star AND why he saw a lot of time in left field last season—J.R. House needed his offensive ability in the lineup.


*You’ll notice also that the Generals tend to have a higher on-base floor, so to speak, in night games than in day games—it’s harder to prepare when you’ve got less time before the game, and that’s always the case with daylight games.

*Check out each guy’s highest split—where is it? For a lot of guys, it’s when they’re ahead in the count. (In this case, 0-0, 1-1, and 3-2 counts are considered “even”; 2-2 is “behind”). Look also at who does well when they’re behind in the count. Jose Vinicio and Jamie Westbrook are freer swingers than their peers—if you’re not afraid to swing, you’re probably inclined to hit better in bad counts, provided you can make contact. (Walks, of course, can’t be drawn in a count where you’re behind.)

Robertson running 2568

*The three guys who have the highest on base percentage with two outs are Daniel Robertson, Alberto Rosario, and Josh Prince. Quick: what do they all have in common? If you’ve been paying attention, you may know that all three have MLB service time. If you’ve been to The Show, you’ve more than likely got both a very high awareness of any situation, and you can execute and/or maintain your plate discipline against strong talent. The Generals are lucky to have a guy like that in each third of their batting order most nights of the week.


Cribbs 9.4% 28.8% .139 .336 3.2 20.3%
DeLuzio 7.1% 23.9% .088 .273 -4.3 16.7%
Flores 11.1% 22.2% .180 .379 14.4 18.1%
Herum 7.0% 13.0% .142 .355 3.0 17.6%
Leyba 9.0% 15.0% .113 .323 0.1 16.1%
Littlewood 14.6% 19.1% .106 .294 -3.4 12.9%
Prince 13.2% 23.2% .135 .376 8.0 27.4%
Robertson 11.2% 12.4% .160 .354 5.9 15.0%
Rosario 6.9% 13.8% .063 .304 -1.3 15.4%
Vinicio 3.9% 24.0% .098 .280 -7.4 9.9%
Westbrook 4.6% 16.9% .194 .357 9.4 17.3%

*Daniel Robertson is the guy closest to having a walk rate that outpaces his strikeout rate, which is great for a table-setter. He’s also shown surprising power, hitting six homers en route to a .160 isolated power mark. That combination of sneaky power and having a good eye at the plate are part of what got D-Rob to the big leagues in four different seasons. You want to prove people wrong as a 33rd round pick? Be efficient and show some pop.

*Galli Cribbs is still a glove-first shortstop, even after batting .351 in April. But wouldn’t you love to see shades of April Cribbs return? If that’s going to happen, he’ll have to reaffirm his plate discipline. After picking up 11 walks in April, Cribbs walked just 13 times over the next two months, which is partly why his numbers have dipped. If he can’t perform more consistently in bad counts (.173 OBP, his lowest split here by far), the only other option is to avoid them entirely. He’s hitting enough line drives to be a nightly contributor, but a strikeout rate near 30%, absent a lot more power, cannot be ignored going forward.

*If you’re hunting for a wild card, the so-called “x-factor,” it might be Marty Herum. Having just returned from an April injury, Herum played only 30 games through July 9, but his wOBA and wRAA are strong, and that’s important. DON’T LET THESE ABBREVIATIONS SCARE YOU, FAM – I’VE GOT YOU!

Think of wOBA as the highest revision of on-base percentage. The “w” part means “weighted,” i.e. not everything weighs the same—singles and doubles, for example, are weighted differently in this formula, as they should be. The reason wOBA is better than slugging percentage is scale. When you hit a triple in your only at-bat, your batting average is 1.000 and your on-base percentage is 1.000, but your slugging percentage is 3.000. Why? Slugging is scaled differently. With wOBA, every offensive result has a specific pre-determined weight, so the final number encompasses everything you’ve done at the plate and spits out a something you can easily frame in the context of the .300-.400 range decimals you’ve seen forever as a baseball fan.

Now, bear with me—you can stick with wOBA if you’d like to get off this sabermetric express train, or you can ride out to one more stop, wRAA. Baseball is about scoring runs, and wRAA uses wOBA as an input to determine the difference in run production between your player and an average player. We’re not talking about literal runs in the “R” column, but all of the offensive events that contribute fractions of a run, summed up into a nice, friendly, zero-scaled numeral. wRAA answers the question: “How many runs has this guy helped us produce beyond an average player’s contribution?”

Marty Herum’s wRAA, unlike his wOBA, is not among the top 3 hitters on the team. This is in part because wRAA works like a counting stat, in that you can collect more wRAA (and also lose wRAA) as you play more games. With that in mind, it makes a huge difference to divide wRAA by each player’s number of games played. In a per-game context, Marty Herum is the Generals’ third-best run producer, sitting at 0.1 wRAA/G behind Flores (0.18) and Prince (0.14).

Do you remember the Generals going 15-2 in April? How about the 26-32 stretch after that, when Herum was on the disabled list for every game except one (May 10, a loss)? If Jackson is going to turn things around from a sub-.500 record in the Second Half (currently 6-13), they’re going to need a positive impact from Herum, not unlike what they got in the First Half from now-Reno-Ace Juniel Querecuto.
