FanGraphs Baseball

Welcome to another episode of Baseball Writer Notices Something Totally Mundane, Starts Thinking Way Too Hard About It, and Turns it Into an Article, brought to you by FanGraphs, WGBH Boston, and Viewers Like You. I’m your host, Bob Vila.

A couple weeks ago, I was at a Phillies-Astros game where Don Mattingly chose to pinch-run for Luis Arraez with Garrett Stubbs. It’s not every day you see a catcher pinch-run for a second baseman, though it made sense for reasons I’ll get into in a second. A week later, I was at home watching a Guardians-White Sox game, and Cleveland manager Stephen Vogt inserted David Fry as a pinch-runner for Patrick Bailey in a high-leverage situation.

Fry came up as a catcher, and while he’s made a handful of appearances behind the plate this year, these days he’s more of a four-corners bat-first guy. Even so, he still runs like a catcher. Still, Vogt — who’s a good manager with exceptional analytical integration with his front office — chose to put Fry’s leaden getaway sticks on the basepaths with the division title on the line.

Back from vacation, I returned to the field Monday for an Instructional League game between the Athletics and Rockies. How is the Instructional League different from the Bridge League, which I’ve covered previously? Both are unofficial leagues with a scrimmage-style setting, but “Instructs” take place after the rest of the minor league schedule has concluded, and typically includes a handful of select players from the various affiliates that the parent club wants to see more of, and maybe the best couple of guys from each org’s DSL squad. So, Bridge League (which takes place after the Draft and Complex League seasons are over but before the rest of the minors are done) features rookie-level players, new draftees, and rehabbers, while Instructional League has more select talent from several different minor league levels, and often includes Arizona Fall Leaguers who are getting ramped up for their looming slate. There isn’t the same kind of internal team video or shared data for this window as there is for regular season affiliated ball, so this makes Instructs particularly useful to see in person.

The Yankees had to make do without Aaron Judge for all of June, July and August due to a stress fracture in his right first rib. With the days on the calendar dwindling and the AL East title still in play — which is no longer the case after the Rays clinched on Tuesday night — Judge bypassed a rehab assignment, but once he returned, he played in just seven games before landing back on the injured list due to a right calf strain. Both the slugger and the team took great pains to avoid discussing the injury’s specificity and timeline for recovery until Tuesday, when manager Aaron Boone revealed that Judge has a “moderate grade” strain, received a platelet-poor plasma injection, and isn’t expected to be available for the team’s Wild Card Series rematch against the Red Sox.

While deadline acquisition Heliot Ramos has heated up after a very slow start to his pinstriped career, the Yankees’ right field situation is one of the more glaring potential trouble spots among American League contenders. As the playoffs approach, teams no longer have a chance to upgrade from outside their organizations and instead must make do with the talent on hand. What follows here is a look at the most vulnerable teams at each position — something of a companion to my annual pre-deadline Replacement Level Killers series, with a focus on the teams that still have a chance to make the playoffs. For the AL, that means the Rays, Yankees, and Red Sox — all of whom have clinched spots — plus the Guardians, White Sox, Rangers, and Astros, who are battling for the other two division titles and the third Wild Card spot. I’ve taken the Blue Jays out of consideration, as their Playoff Odds now start with a zero in front of the decimal. While full-season performances play a significant part here, I’m more concerned with who’s worst now, with injuries and adjustments in mind. Each position has a headliner (or two, if it’s a job share), but at several positions, I’ve noted other teams with concerns. A companion National League piece will follow.

Royalty is all about taking a select few and placing them upon a pedestal for adoration and worship by the faceless masses. And often, when a team wins a title, it happens as a result of star players doing what star players do — making big plays at pivotal moments and swaying outcomes with jaw-dropping feats. But as the championship series of the WPBL’s inaugural season progressed from one game to the next, the stories behind each result weren’t written by the team captains or the players with the most impressive regular-season stats. Rather, a varied cast of unlikely heroes took the stage each night and managed to put on a unique rendition of a show we’ve all seen dozens of times before. We’re all familiar with how a playoff series typically unfolds, and we’ve even seen how it’s gone when these exact teams faced one another during the regular season. And yet, a band of unlikely heroes with representation from both the Los Angeles Queens and the San Francisco Firebells came together to offer us something completely unexpected.

Below we’ll walk through the five-act play that was the WPBL’s championship series, which went the full five games and which the Queens ultimately won, and highlight the unlikely heroes from each game by describing what they did and why their accomplishments were so improbable.

Game 1: Queens 7, Firebells 6

Because their first-round series with the Heights went the full three games, the Queens had just one day off prior to Game 1 of the championship series on Wednesday. Comparatively, the Firebells’ last game was the previous Friday, since their series against the Hunters began one day prior to Queens-Heights and San Francisco dispatched of Boston in a two-game sweep. Michelle Roche — the Queens’ most effective starter — threw 3 1/3 innings in Game 3 against the Heights, and Ayami Sato — their only other pitcher with more than one start during the regular season — threw two innings in Game 3 after covering three innings in Game 2. Out of necessity, Game 1 was a bullpen game for Los Angeles, while the Firebells got to line up their optimal rotation, which meant no. 1 starter Kelsie Whitmore took the ball for San Francisco in the series opener.

Ben Lindbergh and Meg Rowley banter about Meg’s return from vacation and their podcast-producer search, then discuss the uncertain statuses of Aaron Judge, Alex Bregman, and Shohei Ohtani on the precipice of the playoffs, how similar finishes in consecutive seasons can produce extra-disappointing or surprisingly uplifting results (featuring thoughts on the Astros, Diamondbacks, and Cardinals), the Padres’ recent run, Paul Skenes pinning part of the blame for his inconsistent season on the WBC, what to call the Tigers’ rebranded ballpark, managerial moves for the Red Sox and Mets, Cade Cavalli’s extension, business updates involving the Yankees, Angels, and Dodgers, an Ichiro Suzuki sighting, and a pair of weird-lookin’ (hit by) pitches, plus a few follow-ups.

When Aaron Judge is healthy, he’s the most dangerous hitter in baseball. Sometimes I get alarmed at how uncontroversial a statement that is; ours is a sport that so frequently humiliates those who make such sweeping, unequivocal judgments as those.

But the empirical evidence is what it is. Judge has played 150 or more games in a season four times in his career. In those four seasons, he’s led all position players in WAR four times and led the league in wRC+ three times. He’s been named AL MVP three times and finished second once, ahead of some real doozies: Cal Raleigh’s 60-homer year, Bobby Witt Jr.’s 10.5-WAR campaign in 2024, Shohei Ohtani’s best pitching season — in fact, a healthy Judge is the only thing that’s ever trumped a healthy Ohtani in an MVP race.

So again, it’s not uncontroversial to say that when Judge is healthy he’s the best hitter in the world. He has not, however, always been healthy. Least of all this season, when he missed three months with a broken rib. And now, the single-season AL home run king is back on the IL with a calf strain. The timing could not be worse.

Ah, the end of September. For most teams in baseball, it’s a time for planning. Out of the race? It’s time to plan for the future. Playoff spot locked up? Time to plan for October. The Brewers are no exception. They’ve cruised to a postseason bye and look very likely to end the year as the top overall seed. But while the games the rest of the regular season aren’t of huge import to them, one decision is: What to do about Kyle Harrison.

If Jacob Misiorowski hadn’t been the Brewers’ biggest story this year, Harrison would’ve been. After a few tough years in San Francisco and a rocky half-season in Boston, he arrived in Milwaukee in the Caleb Durbin trade and impressed right away. He struck out eight in his first start. He kicked it into overdrive by the end of April. An early summer slowdown notwithstanding, he had spectacular numbers at the All-Star break, and I was surprised he missed earning his first appearance at the Midsummer Classic.

In the end, he wouldn’t have played in the game anyway. The Brewers put him on the IL on July 11 with forearm tightness. When he returned in August, he was down a few ticks of velocity and looked like he was searching for the form that had so befuddled hitters earlier in the year. After a few near-misses and inefficient outings, the wheels fell off in Chicago on August 31; the Cubs tagged him for nine runs in 3.2 innings, courtesy of a gruesome five home runs. In his next start, at Cincinnati on September 6, he gave up six more runs and walked as many as he struck out. Read the rest of this entry »

Ron Coomer was a solid hitter while playing for four teams, mostly the Minnesota Twins, across the 1995-2003 seasons. A corner infielder who took his hacks from the right side, the Chicago-area native counted 92 round-trippers among his 827 base knocks. An All-Star with the Twins in 1999, he later suited up for the Cubs, Yankees, and Dodgers.

He is currently in his 13th season as a color analyst in the Chicago Cubs radio booth. Working along the legendary Pat Hughes, Coomer not only provides insight gleaned from his playing days, he consistently contributes entertaining anecdotes. Given those attributes, he was an ideal candidate for an installment of our Challenging Career Quiz series.

As with most of the dozen players-turned-broadcasters who preceded him, I began by asking who he faced the most times.

“I don’t know,” he replied. “Would it be Scott Karl?”

Coomer wasn’t particularly close with his guess. He matched up against the erstwhile Milwaukee Brewer a total of 25 times, whereas he faced Chuck Finley 45 times.

“Really?” Coomer said upon learning it was the longtime California/Anaheim Angels southpaw, against whom he went 11-for-42 with a pair of home runs. “I remember Chuck very well. I remember getting some hits off him, and I really remember that I got a lesson taught to me when I was a young big league player. He threw me a pitch inside and I blasted it, but hit it way foul at the Metrodome. I thought, ‘Well, he’s not throwing that again.’ I was wrong. He doubled up and struck me out on the same fastball inside. I went, ‘Hmmm, OK. Don’t forget that.’ I think this was my first year in the big leagues.” Read the rest of this entry »
