The Worst Team Defenses Among Contenders

Jordan Johnson-Imagn Images

If you followed along with my Replacement Level Killers series, you’re no doubt familiar with the disheveled state of the Twins. After last year’s epic late-season collapse, Minnesota started slowly, clawed its way back into contention, and then stumbled during a 9-18 June; the team is now 48-51 with 17.5% Playoff Odds, still good enough to qualify for my series highlighting the weakest spots on contenders. Within that series, the Twins made a major league-high five appearances: at catcher, first base, second base, third base, and right field. An underrated part of their struggles is their defense. To the extent that they can still be considered contenders, their glovework stands out as the worst of any playoff hopeful based upon the methodology I used to identify the best team defenses thus far a few weeks ago.

Along with that piece, this is part of my annual midseason dip into the alphabet soup of defensive metrics, including Defensive Runs Saved (DRS), Statcast’s Fielding Run Value (FRV), and our own catcher framing metric (hereafter abbreviated as FRM, as it is on our stat pages). Longtime standby Ultimate Zone Rating has been retired, which required me to adjust my methodology.

On an individual level, even a full season of data isn’t enough to get the clearest picture of a player’s defense. Indeed, it’s not at all surprising that samples of 800 innings or fewer produce divergent values across the major metrics; different methodologies produce varying spreads in runs from top to bottom, spreads that owe something to what they don’t measure, as well as how much regression is built into their systems. Pitchers don’t have FRVs, and DRS tends to produce more extreme ratings (positive and negative) than Statcast. But within this aggregation, I think we get enough signal roughly 60% of the way through the season to justify checking in; I don’t proclaim this to be a bulletproof methodology so much as a good point of entry into a broad topic.

The 2025 Replacement-Level Killers: Designated Hitter

Troy Taormina and Kamil Krzaczynski-Imagn Images

At last we reach the end of my annual series spotlighting the weakest positions on contending clubs. While still focusing upon teams that meet that loose definition of contenders (a .500 record or Playoff Odds around 10%), I’ve also incorporated our Depth Charts’ rest-of-season WAR projections into the equation for an additional perspective. Sometimes that may suggest that the team will clear the bar by a significant margin, but even so, I’ve included them here because the team’s performance is worth a look.

At the other positions in this series, I have used about 0.6 WAR or less thus far — which prorates to 1.0 WAR over a full season — as my cutoff, but for the designated hitters, I’ve limited the list to the teams below zero, both to keep the length manageable and to account for the general spread of value. In the fourth full season of the universal DH, 0.6 WAR represents the median, with 10 teams below zero, 11 between zero and 1.0, and eight with 1.0 or more, with only four of those eight reaching 2.0. By comparison, at this time last year, half the teams in the majors were at 0.0 WAR or less. DHs as a group have hit .239/.322/.422 for a 108 wRC+ this season, the last of which matches 2024’s final figure.

It does appear that an increasing number of teams are investing more playing time in a single DH. From 2022 (the first full-length season with the universal DH) to ’24, the number of players reaching 450 plate appearances in the DH role increased from three to four to seven; this year, we’re on pace for 10. That said, many of the teams on this list are the ones that haven’t found that special someone to take the lion’s share of the plate appearances.

The 2025 Replacement-Level Killers: Left Field & Right Field

Today the Killers list turns the corner — or rather turns to the teams receiving less-than-acceptable production in the outfield corners. While still focusing on clubs that meet the loose definition of contenders (a .500 record or Playoff Odds of at least 10%), and that have gotten about 0.6 WAR or less out of a position thus far (which prorates to 1.0 WAR over a full season), I’ve also incorporated our Depth Charts’ rest-of-season WAR projections into the equation for an additional perspective. Sometimes that may suggest that the team will clear the bar by a significant margin, but even so, I’ve included them here because the team’s performance is worth a look.

As noted previously, some of these situations are more dire than others, particularly within the context of the rest of their roster. I’ve batched the two corners into one supersized roundup because three of the seven teams below the WAR cutoff for left field also make the list for right field, and because there’s plenty of crossover in play with regards to personnel. The capsules are listed in order of their left field rankings first, while noting those crossover teams with an asterisk. As always, I don’t expect every team here to go out and track down upgrades before the July 31 deadline, but these are teams to keep an eye on.

Royals*

Good grief, somehow Royals corner outfielders have combined for -3.8 WAR, suggesting that the 47-50 team would be over .500 if it had found some typically unremarkable replacement level outfielders to fill those posts. Manager Matt Quatraro has used nine left fielders and eight right fielders, with some crossover between the two. Somehow, only one player at each position has managed even a 100 wRC+ in their thin slice of playing time, namely Jonathan India in left and Drew Waters in right. India, who’s played all of 21 games in left, is new to the position at the major league level; his glove is a liability no matter where you put him and he’s hitting just .251/.332/.348 (91 wRC+) overall. Waters, who’s played 41 games in left, 21 in right, and 22 in center, has hit just .243/.288/.316 (66 wRC+) overall, suggesting his 105 wRC+ in 53 PA in right is a fluke. Mark Canha has collapsed to a 49 wRC+ with career worsts in just about every key Statcast category, though his stints on the injured list for an adductor strain and (currently) tennis elbow have possibly contributed to his woes. None of the other principals at either corner has spent time on the IL.

Hunter Renfroe, who began the year as the regular right fielder, was a full win below replacement before he was released in late May. Jac Caglianone, a 22-year-old 50-FV prospect who has taken over right, has been the next-worst, at -0.9 WAR. Caglianone entered the season ranked no. 47 on our Top 100 Prospects list but had never played above High-A; he’s hit a cringeworthy .140/.196/.264 (22 wRC+) in 138 PA while chasing 41.1% of pitches outside the zone. At some point a responsible adult would send him back to the minors for more seasoning despite the occasional 466-foot homer. Instead, he’s 4-for-40 this month including that July 10 shot. Cool, cool.

In eight seasons of doing this series for FanGraphs (plus a handful of times at Baseball Prospectus and Sports Illustrated), I can’t recall even a fringe contender so hamstrung by an inability to find reasonably productive players at offense-first positions. It’s a testament to the quality of the Royals’ pitching and the play of Bobby Witt Jr., Maikel Garcia and Vinnie Pasquantino that this team even has a shred of a chance at a playoff spot. This is the part where I normally suggest potential trade targets who could help shore up the situation; in this case the answer is “just about anyone not already on the Royals roster.” Candidates such as the White Sox’s Andrew Benintendi and the Marlins’ Jesús Sánchez look like Juan Soto and Aaron Judge next to this crowd.

Reds*

Nothing the Reds have done with either outfield corner has worked for very long or very well. Manager Terry Francona has used 10 different left fielders and eight different right fielders, with six players getting time at both. Offseason acquisition Gavin Lux has logged a team-high 34 starts in left while bouncing around to make 30 more at DH, nine at second base, and five at third. Overall, he’s hit .265/.355/.379 (106 wRC+), but his play in left has been, uh, DH-caliber (-6 FRV, -4 DRS in 278.2 innings). Austin Hays, who’s split his time about equally between left (21 starts) and DH (23 starts), has been very effective when available (.287/.323/.517, 124 wRC+) amid three separate IL stints for left calf and left hamstring strains and a left foot contusion; he and Lux have generally shared the left field and DH roles against righties.

Jake Fraley has started 39 games in right, all but one against righties; he’s hit .224/.336/.376 (100 wRC+), but has served IL stints for a left calf strain and a right shoulder sprain, the latter of which he returned from just before the All-Star break. Will Benson has split his time between left (17 starts), right (22 starts), and center (three starts), with just four from that total against lefties; he’s scuffled to a .223/.276/.427 (87 wRC+) line. Of the eight other corner outfielders Francona has tried, only Santiago Espinal has a wRC+ of at least 100 in that capacity, but that’s over just 30 PA, and his overall 63 wRC+ factors into the Reds’ placement on the third base list.

With Hays and Fraley both healthy, the Reds are in better shape than they’ve been for most of the season; the pair has spent just about two weeks together on the active roster (the second half of April). Still, between those two and the everyday play of Lux at one position or another, they’re a bit light (spoiler alert: they’ll be on the DH list as well), with a right-handed bat probably their bigger need. Unlike the Phillies (below), they’re less inclined to add payroll, but as one of the league’s younger teams, they should think in terms of multiple years. Three righties who could be available, the Rangers’ Adolis García, the Orioles’ Ramón Laureano, and the Angels’ Taylor Ward, each have another year of club control remaining; the first two will be arbitration-eligible, the last has a $6.5 million option. Red Sox lefty Wilyer Abreu, who’s got one more pre-arbitration season, offers even more upside and control but will require a greater return.

Phillies*

As noted in Wednesday’s installment, the Phillies rank 27th in the majors in total outfield WAR at 0.3, with left field the weakest of the three positions. Max Kepler spent the better part of a decade as a league-average hitter with a good enough glove to be a two-to-three-win right fielder for the Twins, but last year, he made two trips to the IL and slipped to a 93 wRC+ and 0.9 WAR. The Phillies didn’t overcommit, signing him to a one-year, $10 million deal, but his offense has continued to lag. His 90 wRC+ (.210/.307/.371) is a career low, and in his first taste of left field — the easier of the two corners — his -2 FRV is as well. Kepler’s average exit velocity is about 2 mph higher than last year, with his barrel rate improving from 6.2% to 11.4%, and his hard-hit rate from 36.6% to 44.8%, but he’s fallen 51 points short of his .412 xSLG.

Right fielder Nick Castellanos needs no introduction to readers of this annual series. Four years into a five-year, $100 million deal with the Phillies, his timing remains impeccable: he’s landed here annually. His offense isn’t completely terrible for a change; his 107 wRC+ (.273/.313/.438) is in line with his final 2022 and ’23 lines, and only three points shy of the major league average for right fielders. Alas, he’s a DH stuck in the field because the Phillies already have a better DH in Kyle Schwarber. Castellanos’ defensive metrics are on track to be his worst since 2018; after averaging -9 DRS and -12 FRV in his first three seasons in Philly, he’s at -14 DRS and -12 FRV with 66 games to go.

The Phillies have recently given a bit of playing time in left field to 25-year-old rookie Otto Kemp, an undrafted free agent who hit .313/.416/.594 at Triple-A Lehigh Valley and is at .247/.316/.337 (86 wRC+) with a 28.6% strikeout rate through 98 PA thus far in the majors. Kemp has 30-grade contact skills due to his problems with secondary stuff, and his defense at third base, his primary position in the minors, is shaky. He might work as the short half of a corner platoon, but the Phillies really need to add a quality bat. Abreu, García, and Ward each offer some firepower (not necessarily without flaws), while Benintendi and Sánchez would at least raise the production floor.

Padres

Where have you gone, Jurickson Profar? A nation turns it’s lonely eyes to you… The departure of their 2024 left fielder left a hole that the Padres have tried to fill using 10 different player. The bygone platoon of Jason Heyward and Oscar Gonzalez wasn’t up to the task. What has worked lately, particularly on the offensive side, has been using Gavin Sheets in left. The ex-White Sock has hit .265/.324/.451 (119 wRC+) in 44 games at DH, 34 in left (with all but two of them coming since May 25), and 12 at first base. Historically, the 6-foot-3, 235-pound lefty has been brutal in right field (-23 DRS, -18 FRV in 1543 innings) but has been within one run of average in the two metrics in 263 innings in left thus far. He’s been light against lefties (96 wRC+, compared to 128 against righties), so he could use a platoon partner, particularly one who can also serve as a defensive replacement; neither Brandon Lockridge nor Bryce Johnson have shown themselves to be up to the task, but this shouldn’t be the hardest problem for A.J. Preller to solve at deadline time.

Dodgers

Michael Conforto’s one-year, $17 million deal flew under the radar this past winter given the team’s fancier expenditures, but like those, the early returns aren’t too hot. The 32-year-old Conforto has hit just .184/.298/.322 (80 wRC+) with eight homers and subpar defense in left field (-3 DRS, -3 FRV). July is his first month with a wRC+ of at least 100, albeit in just 38 PA, and there’s no underlying batted ball trend suggesting notable improvement. Indeed, Conforto’s Statcast contact numbers, while still above average, are down relative to last season, and he’s lagging well behind both his .243 xBA and .421 xSLG, with his 99-point shortfall in SLG the seventh-largest in the majors.

While the Dodgers have alternatives in left, Enrique Hernández figures in the third base picture with Max Muncy sidelined, and Andy Pages — whose 205 wRC+ in 44 PA is propping up the offensive numbers here — is better used in center or right. One as-yet unexplored option would be to add rookie Dalton Rushing to the mix. The 24-year-old backstop has hit just .221/.293/.309 (73 wRC+) since debuting in mid-May, but a weekly diet of 10 PA can’t be helping his cause, and he does have 33 games of minor league experience in left.

It’s not inconceivable that the Dodgers cut bait on Conforto, particularly if they have a roster crunch. But so long as their offense is scoring a major league-high 5.33 runs per game, the matter is less urgent than their perennial need for pitching amid so many injuries.

Astros

The Astros haven’t entirely buried the Jose Altuve experiment yet, but the 35-year-old star has started just two of Houston’s last 19 games in left (and 39 overall) compared to four at designated hitter and 13 at second base. His offense (.277/.336/.465, 121 wRC+) has been fine, but his defense at the new position has been brutal (-8 DRS, -4 FRV in 325 innings), and it’s been no picnic at second either (-3 DRS, 0 FRV in 263 innings). His best position these days is probably DH, and with Yordan Alvarez sidelined due to inflammation in his right hand with no clear return date, that option is at least open.

Of the eight other Astros who have played left, the best on both sides of the ball has been Mauricio Dubón, who’s made more starts at second than left (29 versus five) while also filling in at shortstop (where he’s helped to cover for the loss of Jeremy Peña to a broken rib), third, and the other two outfield spots. He’s hitting a comparatively robust .255/.292/.415 (96 wRC+) overall and is, of course, a better defender than Altuve at either post, but he belongs at a position where he can best utilize those defensive skills. The Astro who’d merit a closer look is Zach Dezenzo, but the 6-foot-5, 220-pound rookie was recently transferred to the 60-day IL while recovering from a capsule strain in his left hand. He’s just 6-for-47 while playing left but is hitting .245/.321/.367 (96 wRC+), with a 16.4% barrel rate and a .440 xSLG offsetting his 33.9% strikeout rate. He’s eligible to return in August, so the Astros may push forward with their current jumble and hope he can help later. Still, with apologies to Cooper Hummel, Taylor Trammell, et al, this team needs a garden-variety left fielder who can hit a lick and catch the ball.

Diamondbacks

Lourdes Gurriel Jr. is now in his third season as Arizona’s left fielder. While his .251/.299/.421 slashline represents drops of 28 points of AVG, 23 points of OBP, and 14 points of SLG relative to last year — for a 10-point drop in wRC+ (from 108 to 98) — his average exit velocity, barrel rate, and hard-hit rate are virtually unchanged, and his xBA, xSLG, and xwOBA have only fallen by six or seven points. Aside from a 4.5-percentage point drop in strikeout rate, resulting in more batted balls, nothing’s really changed for him on the offensive side. He’s on this list because of a bit of bad luck here and a dip in defensive metrics there (from 3 DRS to -6, and from 1 FRV to -2), but he’ll probably remain the everyday left fielder unless the Diamondbacks clear out some outfield depth and cut salary ahead of the trade deadline — in which case he could wind up with another team on this list.

Guardians

Originally drafted and developed by the Guardians, Nolan Jones made four Top 100 Prospects lists (2019–22) before being traded to the Rockies in November 2022. Following a strong rookie season in Colorado (20 homers, 20 steals, 137 wRC+, 3.7 WAR), he battled injuries — most notably a lower back strain — and struggled in 2024, hitting just .227/.321/.320 (69 wRC+) with three homers. The Guardians reacquired him in March and have generally started him against righties either in right (45 times) or center (12 times), with nine starts against lefties spread across the three outfield positions. Unfortunately, the lefty-swinging 27-year-old’s offense hasn’t returned; he’s batting just .229/.319/.330 (87 wRC+), though as noted in the center field installment, he’s hitting the ball harder than those results suggest, with a 91.5-mph average exit velocity (3.3 mph higher than last year), an 8% barrel rate, and a 46.3% hard-hit rate. He’s cut his groundball rate, is pulling the ball more often, and has even shaved his strikeout rate to 26.5%. The 95-point gap between his .425 xSLG and his actual mark is tied for the majors’ ninth-largest.

Jones could use some better luck and a better supporting cast. Jhonkensy Noel plummeted from last year’s 118 wRC+ to zero — yes, a 0 wRC+ — with a .140/.162/.215 slashline, earning him a ticket back to Triple-A Columbus. Current platoon partner Johnathan Rodríguez has been only slightly better (.140/.189/.220, 12 wRC+). Given their 46–49 record and other trouble spots (including shortstop and center field), the Guardians may wind up selling or holding, but one trade candidate who would make sense is Laureano, who spent parts of 2023 and ’24 with the team. The Guardians did release him last May, but his 135 wRC+ for the Braves and Orioles since then suggests he’s worth another look.

Mariners

The early-April loss of starting right fielder Victor Robles to a fracture of the humeral head in his left shoulder cost the Mariners a valuable catalyst. Luke Raley took over the position, but he strained his oblique in late April, missed seven weeks, and upon returning took over the long half of a first base platoon. Leody Taveras came and went. Fortunately for the Mariners, Dominic Canzone arrived from Triple-A Tacoma and has more or less saved the day. The 27-year-old lefty, who’s closed up his stance somewhat and is swinging the bat harder, has hit a sizzling .319/.340/.564 (158 wRC+) in 97 PA. Yes, he’s chasing nearly 38% of pitches outside the zone and walking just 3.1% of the time, but he’s also barreling the ball 15.6% of the time, and both his .300 xBA and .564 xSLG are in line with his actual numbers. He’ll cool off eventually, but currently this doesn’t look like a serious problem for the Mariners, and there’s still hope that Robles can return in September to provide support.

Cardinals

Jordan Walker entered the 2023 season as a 60-FV prospect ranked no. 12 on our Top 100 list, but in parts of three seasons, he’s produced diminishing returns, including a meager .210/.267/.295 (60 wRC+) with a 33% strikeout rate in 191 PA this season. He’s been largely absent from the lineup since late May, first missing a couple of weeks due to inflammation in his left wrist, then enduring a bout of appendicitis in late June. While on his latest rehab assignment, the Cardinals are again tinkering with his swing, but so far, he’s gone just 7-for-46, albeit with five extra-base hits, at Double-A Springfield and Triple-A Memphis.

Walker’s still just 23, but it’s fair to wonder if he’ll ever live up to that lofty prospect billing, at least in St. Louis. The good news for the Cardinals is that Alec Burleson has taken over right field and absolutely raked, hitting .333/.374/.592 (158 wRC+) in 138 PA. Overall, the 26-year-old lefty has hit .293/.340/.466 (125 wRC+), though he could use a platoon partner; he has a career 52 wRC+ against southpaws.

Twins

Matt Wallner can mash. In 2023 and ’24 combined, he hit .254/.371/.515 (148 wRC+) with 27 homers in 515 PA for the Twins, even while striking out a whopping 34% of the time and spending chunks of both seasons in Triple-A. The Twins hoped that he could approximate that production across a full season, but a mid-April hamstring strain curtailed his strong start; he didn’t return until May 31 and has managed just a 91 wRC+ since. His overall line (.205/.299/.449, 107 wRC+ with 10 homers) in 41 games in right and 12 at DH rates as a disappointment. He’s getting under too many balls; his 21.8% infield fly ball rate is the second-highest of any player with at least 150 PA. Trevor Larnach, who covered right for part of Wallner’s absence and has lately been sharing the job, has hit a modest .245/.311/.415 (102 wRC+) while playing 34 games in right plus another 59 at DH and in left field. Willi Castro, the only other Twin with at least 20 PA as a right fielder, has struggled in his time there (28 games but just 15 starts) but has hit for a 124 wRC+ overall in his utility role.

Considering this is now the fifth position at which the Twins have made a Killers list, it’s clear they’ll have to solve some problems from within in order to challenge for a playoff spot. Despite his struggles, Wallner’s recent track record provides more reason for optimism than, say, Ty France at first base.


Sunday Notes: Rodney Linares Looks Back at Jose Altuve In Rookie Ball

Jose Altuve is having a Cooperstown-worthy career. Since debuting with the Houston Astros in 2011, the 35-year-old second baseman has logged 2,329 hits, including 246 home runs, while putting up a 129 wRC+ and 59.2 WAR. A nine-time All-Star who has won seven Silver Sluggers and one Gold Glove, Altuve captured MVP honors in 2017.

Turn the clock back to 2008, and the 5-foot-6 Puerto Cabello, Venezuela native was 18 years old and playing stateside for the first time. His manager with the rookie-level Greeneville Astros was Rodney Linares.

I recently asked the now-Tampa Bay Rays bench coach for his memories of the then-teenaged prospect.

“One guy that doesn’t get a lot of credit for Altuve is [current St. Louis Cardinals first base coach] Stubby Clapp, who’d been my hitting coach the year before,” Linares told me. “He always talked about Altuve, because he’d had him in extended spring. He was like, ‘You’ve got to watch this kid; this kid is going to be really good.’ I used to tell Stubby, ‘You think that because you’re small and played in the big leagues, anybody who is small can play.’”

Linares recalls the Astros organization’s wanting him to play 20-year-old Albert Cartwright at second, prompting him to tell Altuve ‘Go to short, go to third, go to left field. I’m going to make sure that you get your at-bats.” Read the rest of this entry »


Houston Astros Top 38 Prospects

Troy Taormina-Imagn Images

Below is an analysis of the prospects in the farm system of the Houston Astros. Scouting reports were compiled with information provided by industry sources as well as my own observations. This is the fifth year we’re delineating between two anticipated relief roles, the abbreviations for which you’ll see in the “position” column below: MIRP for multi-inning relief pitchers, and SIRP for single-inning relief pitchers. The ETAs listed generally correspond to the year a player has to be added to the 40-man roster to avoid being made eligible for the Rule 5 draft. Manual adjustments are made where they seem appropriate, but we use that as a rule of thumb.

A quick overview of what FV (Future Value) means can be found here. A much deeper overview can be found here.

All of the ranked prospects below also appear on The Board, a resource the site offers featuring sortable scouting information for every organization. It has more details (and updated TrackMan data from various sources) than this article and integrates every team’s list so readers can compare prospects across farm systems. It can be found here.

The 2025 Replacement-Level Killers: Introduction & First Base

Kamil Krzaczynski-Imagn Images

In a race for a playoff spot, every edge matters. Yet all too often, for reasons that extend beyond a player’s statistics, managers and general managers fail to make the moves that could improve their teams, allowing mediocre production to fester at the risk of smothering a club’s postseason hopes. In Baseball Prospectus’ 2007 book, It Ain’t Over ‘Til It’s Over, I compiled a historical All-Star squad of ignominy, identifying players at each position whose performances had dragged their teams down in tight races: the Replacement-Level Killers. I’ve revisited the concept numerous times at multiple outlets and have adapted it at FanGraphs in an expanded format since 2018.

When it comes to defining replacement level play, we needn’t hew too closely to exactitude. Any team that’s gotten less than 0.6 WAR from a position to this point — prorating to 1.0 over a full season — is generally in the ballpark, though my final lists also incorporate our Depth Charts rest-of-season projections, which may nose them over the line. Sometimes, acceptable or even above-average defense (which may depend upon which metric one uses) coupled with total ineptitude on offense is enough to flag a team. Sometimes a club may be well ahead of replacement level but has lost a key contributor to injury; sometimes the reverse is true, but the team hasn’t yet climbed above that first-cut threshold. As with Supreme Court Justice Potter Stewart’s definition of hardcore pornography, I know replacement level when I see it. Read the rest of this entry »

Recently, I’ve had to re-evaluate a strongly held belief. It’s an important thing for responsible adults to do every now and then; even if the opinion wasn’t wrong at the time, conditions can change. And I’m not too proud to identify such a situation now.

Here’s the old take, the one I’m revising now: Jeremy Peña is the most overrated player in baseball. At the time, it made sense. But it definitely doesn’t now. Read the rest of this entry »


Despite High-Profile Injuries and Struggles, the Astros are Breathing Down the Mariners’ Necks

Thomas Shea-Imagn Images

When the Astros awoke on May 7, they were 17-18 and had just slipped into fourth place in the AL West. They had recently placed Yordan Alvarez — who had struggled mightily to that point — on the injured list with what had been diagnosed as a muscle strain in his right hand. First baseman Christian Walker, their big free agent addition, was scuffling along below replacement level, and both new left fielder Jose Altuve and the group that replaced him at second base were playing every bit as badly. Meanwhile, their already-thin rotation had been further compromised by the loss of Spencer Arrighetti. But even while receiving more bad news on Alvarez, and losing two more starters — Ronel Blanco and Hayden Wesneski — to Tommy John surgery, the Astros have turned things around, winning 15 of 24 and briefly sneaking into first place in the AL West.

At this writing, the Astros are now 32-27, and have trimmed the Mariners’ division lead from four games to half a game:

Change in Astros’ Playoff Odds
Date W L W% GB Win Div Clinch Bye Clinch WC Playoffs Win WS
Thru May 6 17 18 .486 4 17.4% 9.9% 28.3% 45.6% 2.6%
Thru June 2 32 27 .542 0.5 42.2% 14.5% 25.3% 67.5% 4.2%
Change +24.8% +4.6% -3.0% +21.9% +1.6%

By comparison, the Mariners started 21-14, but have gone 11-12 since. Since May 6, the Astros have won four series (against the Reds, Royals, Mariners, and A’s), lost one (Rays), and split two (Rangers and Rays). They took three out of four from the Mariners at home from May 22-25, capped by Walker’s walk-off two-run homer off Casey Legumina on May 25. That was one of three walk-off victories during that span; Isaac Paredes‘ solo homer off the Royals’ John Schreiber on May 13 and Yainer Diaz’s solo homer off the Rays’ Garrett Cleavinger on May 30 were the others. The latter shot lifted the Astros’ record to 31-26, allowing them to sneak past the Mariners and into first place, but since then, Seattle beat Minnesota in each of its next two games while Houston split a pair with Tampa Bay, restoring the Mariners to first place by the barest of margins:

Christian Walker Hasn’t Fixed the Astros’ First Base Problem

Troy Taormina-Imagn Images

When the Astros signed Christian Walker to a three-year, $60 million deal in December, it felt like a reasonable solution to a longstanding problem. The Astros have rarely gotten good production from their first basemen in the past decade, and while Walker hasn’t quite been All-Star caliber, in recent years he’s generally provided solid offense with exceptional defense for the position. So far this season, he’s struggled mightily, which unfortunately for the Astros has come at a time when other key players have also failed to hit, and the rotation has weathered numerous injuries as well.

Last year, Walker hit .251/.335/.468 (119 wRC+) with 26 homers and 3.0 WAR for the Diamondbacks, while over the past three seasons, he averaged 32 homers, a 120 wRC+, and 3.6 WAR; his 2024 shortfalls mainly owed to his missing a month due to an oblique strain. Even with time missed, that 2024 production looks like the second coming of Jeff Bagwell next to the .226/.291/.360 (87 wRC+) performance of Astros first basemen last year, with 18 homers but -1.4 WAR, a total that was somehow not quite as bad as the first basemen of the Rockies and Reds. Starter José Abreu crashed and burned and was released in mid-June despite only being about halfway through his three-year, $58 million deal. Thereafter, Jon Singleton did the bulk of the first base work, sharing the job with Yainer Diaz and Victor Caratini on days when one or the other wasn’t catching. It wasn’t great, but it at least stopped the bleeding in that Abreu alone produced -1.5 WAR, while the rest — a group that also included Zach Dezenzo, Mauricio Dubón, and three players who made a single appearance at the position — netted 0.1 WAR.

As Michael Baumann pointed out when Walker signed in December, first base has been a multiyear problem for the Astros. During the 2022-24 span, only three teams had lower WARs at a single position — right field for the White Sox, Rockies, and Pirates — than the Astros’ -2.7 WAR at first. Over the past decade, Yuli Gurriel was the only Astros first baseman to exceed 2.0 WAR in a single season (he did it twice), and five times in the past six seasons, the team’s regular or co-regular first baseman finished with negative WAR.

Five Things I Liked (Or Didn’t Like) This Week, May 23

D. Ross Cameron-Imagn Images

Hello, and welcome to another edition of Five Things I Liked (Or Didn’t Like) This Week. I’ll keep the introduction short today, because I’m getting ready to travel to St. Louis for a game with my dad and uncle. There’s a Masyn Winn bobblehead ticketed for my memorabilia shelf – and a pile of enjoyable plays to recap before I can go get it. So, of course, thank you to Zach Lowe of The Ringer, whose NBA columns of likes and dislikes inspired this one, and let’s get started.

1. The Weekend of Wilmer
I have a soft spot for Wilmer Flores through a sheer fluke of geography. I lived in New York during his Mets tenure, and I moved to San Francisco around the same time he did. His walk-up music has been the same for the last decade: the Friends theme song. It’s a fan favorite and even comes with a good story. He’s the quintessential role player, a guy that most teams would love to have but no team needs to have. He’s been pitching in across the diamond, albeit in decreasingly difficult defensive roles, that whole time. With the exception of a down 2024, he’s been consistently valuable, but he’s never been a star – the closest thing I know to a Wilmer Flores highlight is his charming sadness when he thought he was getting traded.

For just one weekend, though, that all changed. Flores has been improbably dueling with Aaron Judge for the major league RBI lead throughout the first eight weeks of the season. RBI might not be a great predictive stat, and it might not be a great stat overall, but it definitely matters to players. Fancier versions of measuring contextual offense – WPA, RE24, and so on – all think that Flores has been a top 10 run producer this year, too. He’d fallen behind Judge by just a hair in those races – and probably has no chance at keeping up all season. I mean, have you seen Aaron Judge? But none of that mattered when the Giants played the A’s last weekend.
