It’s been a frustrating season for Mark Vientos. After two years of trying to stick with the Mets, he broke out by hitting 27 homers in 111 games last season, and handled third base well enough to look as though he’d locked down a regular job. Yet this year, he’s regressed on both sides of the ball, and on Tuesday night in Los Angeles, he added injury to insult when he strained his right hamstring. The silver lining is that the 25-year-old slugger will get a chance for a reset once he’s healthy, and in his absence, the Mets have an opportunity to sort through their talented but still largely unproven assortment of young infielders.

Vientos’ injury occurred in the top of the 10th inning in Monday night’s opener of a four-game NLCS rematch between the Mets and Dodgers in Los Angeles; the series was an exciting one full of late-inning lead changes, with the two teams emerging with a split and three games decided by one run. Los Angeles had tied Monday’s game in the bottom of the ninth on a Shohei Ohtani sacrifice fly, and New York answered by scoring runs with back-to-back hits to start the 10th. With two outs and runners on the corners, Vientos had a chance to break the game open. He’d been hitting the ball hard lately but not getting great results, and when he smoked a 97-mph grounder to the right of shortstop Hyeseong Kim, it appeared to be more of the same. Kim reached the ball before it cleared the infield, but his throw to first base was an off-line one-hopper. It didn’t matter, as Vientos had fallen down before making it halfway down the line, because his right hamstring seized up.

On Tuesday, the Mets placed Vientos on the injured list and sent him back to New York to determine the severity of the injury. Manager Carlos Mendoza said on Wednesday that Vientos has a low-grade hamstring strain and is expected to receive treatment for 10-14 days before resuming baseball activities. To replace him on the roster, the Mets recalled 24-year-old Ronny Mauricio from Triple-A Syracuse. The former Top 100 prospect (no. 44 in 2022, and no. 90 in ’23, both as a 50-FV prospect) missed all of last season due to a right anterior cruciate ligament tear suffered during winter ball in February 2024. More on him below, but first, Vientos’ struggles are worth a closer look. Read the rest of this entry »

Royce Lewis almost had another grand slam. With the bases loaded in the top of the seventh inning in Sacramento on Tuesday night, A’s righty Tyler Ferguson left a sweeper on the outside edge of the strike zone, and the Twins third baseman — who two years ago hit four grand slams in an 18-day span — didn’t miss it. A’s center fielder Denzel Clarke couldn’t reach the 100-mph, 392-foot drive into the left-center gap in time. Instead, both Clarke and the ball caromed off the wall in quick succession, the sphere a couple feet short of leaving the yard but still good enough to produce a two-run double that expanded the Minnesota lead to 8-3 and finally broke Lewis’ latest string of futility after 32 at-bats.

“It was good to see the ball hit the grass or the dirt [or] the wall,” Lewis said. “Just anything other than a glove.”

Lewis, who turns 26 on Thursday, has become all too familiar with such grueling stretches. This is his third time since the start of last September that he’s endured a hitless streak of at least 22 at-bats, though unlike the first two, he was at least hitting the ball reasonably hard during this one: Read the rest of this entry »

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:

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:

The Dodgers have had some impressive successes in recent years when it comes to acquiring pitchers who have struggled or failed to distinguish themselves elsewhere and then helping them flourish. Tyler Anderson made his first All-Star team as a Dodger in 2022, at his fifth stop in seven seasons. Evan Phillips owned a 7.26 career ERA before being plucked off waivers in 2021, and has since become a dominant part-time closer. Last summer Michael Kopech went from getting knocked around with the White Sox to closing games for the Dodgers within three weeks of being traded. Anthony Banda, Ryan Brasier, Andrew Heaney… the list goes on. Beset by pitching injuries yet again, on Thursday, Los Angeles acquired Alexis Díaz from the Reds with an eye toward helping him recover the form that made him an All-Star just two years ago.

The 28-year-old Díaz, the younger brother of Mets closer Edwin Díaz by two and a half years, has regressed considerably since his standout rookie campaign with the Reds in 2022. He spent the month of May pitching for Cincinnati’s Triple-A Louisville affiliate after a left hamstring injury suffered in spring training compromised his mechanics and displaced him from closer duty. The deal — which went down the day before the Dodgers announced that Phillips will undergo Tommy John surgery next week — sent 2024 draft pick Mike Villani to the Reds.

The Reds drafted Díaz in the 12th round in 2015 out of Juan Jose Maunez High School in Naguabo, Puerto Rico. His climb to the majors was slowed by 2016 Tommy John surgery and the coronavirus pandemic; he didn’t even reach Double-A until 2021. He broke camp with the Reds the following spring and allowed just one run and seven hits in his first 17 1/3 innings — capped by his first career save — while striking out 21. By late August, he was the primary closer, albeit on a team bound for 100 losses. He finished the year with a 1.84 ERA, a 32.5% strikeout rate, and 10 saves in 63 2/3 innings, a performance that helped him place fifth in the NL Rookie of the Year voting.

As one-half of the majors’ most productive catching tandem, Carson Kelly doesn’t have enough plate appearances to qualify for the batting title, but like the Dodgers’ Will Smith, he’s been incredibly productive so far, particularly with runners in scoring position. Unlike Smith, he doesn’t have a lengthy track record of success; in parts of 10 major league seasons with five teams, Kelly has not only never made an All-Star team, he’s only played 100 games in a season twice, and finished with a 100 wRC+ or better just twice. But thanks to some changes to his swing mechanics over the past couple of seasons, he’s in the midst of a breakout campaign for the NL Central-leading Cubs.

The 30-year-old Kelly is hitting .290/.412/.589 with nine homers and a 179 wRC+ in 131 plate appearances. He’s started 28 of the Cubs’ 56 games behind the plate, while Miguel Amaya started 25 before landing on the injured list this past weekend due to an oblique strain, an injury that interrupted a promising start to the 26-year-old backstop’s season. Though Kelly homered after replacing Amaya in Saturday’s loss to the Reds, he was limited to a single late-inning cameo over the next three days due to an unspecified illness before returning to the lineup on Wednesday night. Instead of recalling 21-year-old prospect Moisés Ballesteros, who spent five games DHing for the Cubs earlier this month but whose defense needs more refinement, the Cubs brought up Reese McGuire from Triple-A Iowa to replace Amaya on the roster; he started all three games while Kelly was ailing, homering twice in his season debut against the Reds. All told, the trio of Cubs catchers has been great offensively:

In Shohei Ohtani, Mookie Betts, and Freddie Freeman, the Dodgers don’t lack for superstars with potent bats, but so far this season, Will Smith is swinging — and, notably, not swinging — just about as well as any of them. The two-time All-Star catcher is off to an exceptionally hot start, particularly with runners in scoring position, and the Dodgers recently shook up their roster with an eye towards helping him maintain a high level of production later into the season.

The 30-year-old Smith is hitting .333/.456/.511, good enough to lead the NL in on-base percentage and to rank third in wRC+ (175) behind only Freeman (191) and Ohtani (182). Often batting ahead of either Max Muncy or Michael Conforto — both of whom have struggled thus far this year — he’s been pitched around to some degree, and he’s shown exceptional plate discipline:

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.

After missing significant chunks of the past three seasons due to injuries — including all but 26 games last year — Trevor Story has been healthy enough to play in 48 of the Red Sox’ first 51 games. He hit well over the first few weeks of the season, but lately he’s fallen into a deep slump. With Boston struggling to climb above .500 but awash in promising young players, he may wind up fighting for his job.

The 32-year-old Story entered this season having played just 163 games since the Red Sox signed him to a six-year, $140 million deal in March 2022. He played just 94 games in 2022 due to a hairline fracture in his right wrist and a contusion on his left heel, then just 43 in ’23 after undergoing internal brace surgery to repair a torn ulnar collateral ligament, and 26 last year before fracturing the glenoid rim and tearing the posterior labrum of his left shoulder. That’s not only a lot of time missed — basically two seasons out of three — but it’s also time missed at a pivotal juncture in his career. Even without catastrophic injuries, not many players are the same at 32 as they were at 28, and the version of Story capable of producing at least 20 homers and 20 steals while providing strong defense at shortstop may be gone.

Through Wednesday, Story has hit for just a 65 wRC+, the seventh-lowest mark among AL qualifiers. That’s bad enough, but his recent performance looks even even worse if we simply split his game log down the middle, with 24 games played on each side:
