Vientos was diagnosed with a low-grade strain in his right hamstring Wednesday, Anthony DiComo of MLB.com reports.

Now that the team has determined the severity of Vientos' injury, the plan is for him to rest and receive treatment for 10-14 days before returning to baseball activities. The 25-year-old had been splitting reps between third base and designated hitter before getting injured, and his absence has allowed the Mets to take a closer look at top prospect Ronny Mauricio.

Tena is out of the lineup for Wednesday's game against the Cubs, Mark Zuckerman of MASNSports.com reports.

Tena had started in each of Washington's last seven games while the Nationals faced right-handed pitchers, but he'll hit the bench Wednesday with southpaw Matthew Boyd taking the hill for the Cubs. Platoon mate Amed Rosario will step in at third base in place of Tena, who went 7-for-23 with five extra-base hits (four doubles, one triple), a 5:5 BB:K, six runs and four RBI over that seven-game stretch.

Chapman went 1-for-3 with a double and a walk in Tuesday's 3-2 extra-inning loss to San Diego.

Chapman lined a double into left field during the third inning and has now recorded at least one hit in seven of his last 10 games. During that span, the third baseman is slashing .324/.439/.500 with three runs scored, three doubles, one home run and a 6:6 BB:K across 41 plate appearances. The 32-year-old is now slashing .236/.357/.425 with 30 runs scored, 26 RBI, 10 home runs, 10 doubles, five stolen bases and a team-high 39 walks over 252 plate appearances this season.

Mauricio went 0-for-4 with a strikeout in Tuesday's extra-inning loss to the Dodgers.

Getting the start at third base and batting seventh in his 2025 debut. Mauricio grounded into a double play in the second inning and looked foolish chasing a Clayton Kershaw curveball in the dirt in the fourth, but he's hardly the first hitter to have trouble squaring up the future Hall of Famer. Mauricio could be in line for significant playing time while Mark Vientos (hamstring) is sidelined, platooning with Brett Baty at the hot corner while also seeing action at second base and DH. Mauricio won't match the absurd .515/.564/.818 slash line with three homers and four steals he posted in 39 plate appearances at Triple-A Syracuse, but the 24-year-old has intriguing fantasy upside.

Durbin is not in the lineup for Wednesday's contest in Cincinnati.

Durbin had made 17 straight starts from May 14 through Sunday but now finds himself on the bench for the second time in the Brewers' three-games series in Cincinnati. The Brewers haven't indicated that Durbin is dealing with an injury, but fantasy managers may still want to confirm that he's back in the lineup Friday, when Milwaukee kicks off its three-game series with San Diego. Andruw Monasterio will spell Durbin at third base Wednesday.

High-A Dayton activated Collier (thumb) from the 60-day injured list Tuesday.

Collier was not in the lineup for Dayton's 5-4 loss to Lansing on Tuesday, but he appears to be healthy again after suffering a torn UCL in his left thumb during spring training and requiring surgery. He was cleared to begin a rehab assignment in the rookie-level Arizona Complex League on May 19, playing in 10 games and accumulating 42 plate appearances. Though he'll remain with Dayton for the time being, MLB.com relays that Collier is expected to move up to Double-A Chattanooga in short order.

Muncy went 2-for-4 with two home runs and three RBI in Tuesday's 6-5 extra-inning win over the Mets.

Muncy is up to nine homers this season, with six of them coming over his last seven games. In that span, he has gone 9-for-22 (.409) with 14 RBI. He supplied a two-run homer in the first inning Tuesday and then delivered the game-tying run with a solo shot in the ninth. Muncy has slashed .230/.350/.432 with 35 RBI, 19 runs scored, two stolen bases, eight doubles and a triple over 57 contests in 2025. This power surge should help the third baseman maintain his strong-side platoon role at the hot corner, and he even got a start versus a lefty (Ryan Yarbrough) on Sunday.

Machado went 4-for-4 with a walk and two RBI in Tuesday's 3-2 extra-inning win over the Giants.

Machado delivered a clutch hit, driving in both runs with a two-out, bases-loaded single in the ninth inning to tie the game. He has hit safely in nine of his last 12 contests, but he had gone seven games without a multi-hit effort prior to Tuesday. The big performance lifted his batting average back up to .315 with an .869 OPS, seven home runs, 29 RBI, 40 runs scored, seven stolen bases and 17 doubles through 59 contests this season.

Baty isn't in the lineup for Tuesday's game against the Dodgers.

Baty will get a chance to rest Tuesday after going 1-for-4 during Monday's series opener. While he sits, Ronny Mauricio will get the nod at the hot corner and bat seventh.

The Mets called up Mauricio from Triple-A Syracuse on Tuesday, Jorge Castillo of ESPN.com reports.

As expected, Mauricio is getting a promotion as Mark Vientos (hamstring) heads to the 10-day injured list. Mauricio struggled a bit initially after recovering from multiple knee surgeries, as he hit below the Mendoza Line for Single-A St. Lucie and Double-A Binghamton. Following the initial struggles, he has been stellar for Triple-A Syracuse with a 1.382 OPS, three homers and four stolen bases across 39 plate appearances. The infielder is starting at third base for the Mets on Tuesday and is batting seventh, but his role with the big-league club may be limited.
