Mack went 1-for-4 with a walk, a two-run home run and a second run scored for Triple-A Jacksonville on Wednesday.

The 22-year-old backstop walked it off for the Jumbo Shrimp in the bottom of the 10th inning, giving Mack his 20th homer of the year between Double-A and Triple-A. He's gone yard in four straight games, and over his last 12 contests for Jacksonville he's slashing .325/.383/.950 with 10 of his 13 hits (two doubles, a triple and seven homers) going for extra bases. The presence of Agustin Ramirez ahead of him on the organizational depth chart complicates his timeline, but Mack appears ready to make his big-league debut in 2026, and he could be competing for a 26-man roster spot in spring training.

Kelly went 2-for-5 with a solo home run in Wednesday's 3-2 win over Atlanta.

Kelly continued his recent power surge, as he now has four home runs over his last six games. During that span, he's also tallied seven RBI and he's sporting a 1.058 OPS. Kelly now has 17 long balls for the season, which puts him within one of his previous career high. The Chicago catcher has already set a new career high with 50 RBI this year.

Stephenson started at catcher and went 0-for-4 in Wednesday's 2-1 win over the Padres.

Stephenson, who recently returned from a fractured thumb, was in the starting lineup for a second straight game. It was the first time that he played in back-to-back contests since his return, and Stephenson operated as the catcher in both. Since returning, he's 2-for-14 with a double, a home run and four RBI over five games.

Diaz went 2-for-4 with a solo home run and two RBI on Wednesday against the Blue Jays.

Diaz came through with a clutch home run, delivering a solo home run in the ninth inning to put the Astros up for good. He has multiple hits in three of his last four starts, recording three extra-base hits, six RBI and two runs scored. Diaz now has 19 home runs on the season and will have the chance to reach 20 long balls for the second time in three big-league campaigns.

Smith was scratched from the lineup ahead of Wednesday's game against Colorado due to right hand soreness.

Smith recently missed five games after getting hit on the hand by a pitch last Wednesday, and manager Dave Roberts has said that it will be something the 30-year-old backstop will have deal with for the rest of the season. While Smith takes a day off to nurse his hand, it will be Ben Rortvedt behind the plate catching for Blake Snell.

Langeliers went 2-for-4 with a solo home run, a double and an additional run scored in Wednesday's 5-4 win over the Red Sox.

Langeliers opened the scoring in the first inning with a homer off Payton Tolle before leading off the bottom of the ninth with a double off Aroldis Chapman, eventually coming around to score the winning run. The 27-year-old Langeliers is up to 30 home runs for the first time in his four-year MLB career. Overall, he's slashing .266/.314/.536 with 68 RBI, 65 runs scored and six steals across 471 plate appearances this season.

Crooks isn't in the lineup for Wednesday's game against the Mariners.

It initially seemed like Crooks would take over as the Cardinals' primary backstop to close out the regular season, but a 2-for-17 start to his MLB career will now cause him to miss his third start in four games. Pedro Pages will start behind the plate instead Wednesday, and it seems likely that the two players will split time at catcher during the final stretch.

Feduccia is out of the lineup for Wednesday's game against the White Sox, Ryan Bass of FanDuel Sports Network Sun reports.

Feduccia will get a breather Wednesday after he had started behind the plate in three of the Rays' previous four contests. Nick Fortes will handle catching duties.

Contreras was held out of Wednesday's game against the Rangers due to a bruised forearm, Adam McCalvy of MLB.com reports.

Contreras was initially in the Brewers' starting lineup after taking a pitch off his forearm Tuesday, but the team instead erred on the side of caution and subbed him out for Danny Jansen. Contreras will have an extra day off to rest before Milwaukee returns to play Friday versus St. Louis, at which point the Brewers will re-evaluate him.

Fermin isn't in the lineup for Wednesday's game against the Reds.

Fermin will get a day to reset Wednesday after going 0-for-5 with two strikeouts across the first two games of the series. Elias Diaz will fill in as the Padres' backstop and bat ninth.
