Cason underwent Tommy John surgery this week, Andrew Parker of Beyond the Monster reports.

Cason pitched in just one game in the rookie-level Florida Complex League back in May and had been sidelined ever since due to arm fatigue. The 19-year-old now faces a lengthy rehab that will likely keep him off the mound until the 2027 campaign. Cason was an eighth-round pick in the 2024 Draft and is a two-way prospect at shortstop and pitcher.

Wilson (forearm) will begin a rehab assignment with Triple-A Las Vegas on Saturday, Martin Gallegos of MLB.com reports.

Wilson was cleared for full baseball activities earlier this week and is now ready to test things out in a game setting. The rookie shortstop has been shelved since late July with a fractured left forearm. Because Wilson has only been sidelined for a few weeks, his rehab assignment should be brief.

Pena went 1-for-4 with a solo home run Wednesday against the Red Sox.

Pena led off the home half of the first inning with his 13th home run of the season and second since he was activated from the injured list at the start of August. In 11 games since his return, he's also chipped in five RBI, four runs scored and two stolen bases while hitting .289.

Arias went 1-for-3 with a three-run home run in Wednesday's 13-4 loss to the Marlins.

Arias tied the game at 4-4 with a three-run blast off Eury Perez in the fourth inning. In 16 games since returning from the injured list July 26, the 25-year-old Arias has gone 15-for-58 (.259 average) with three homers, 12 RBI, five runs scored and a stolen base. For the year, he's slashing .236/.290/.393 with nine home runs, 43 RBI, 33 runs scored and four steals across 342 plate appearances.

Correa is not in the lineup for Wednesday's contest against the Red Sox.

It's the first day off for Correa since he was traded back to the Astros at the deadline. Houston will have Ramon Urias at third base and batting seventh in Wednesday's rubber match with Boston.

Pena went 3-for-5 with a stolen base during Tuesday's 14-1 loss to Boston.

Pena produced one-third of Houston's hits during the blowout -- all singles -- and notched his 17th stolen base of the campaign. The shortstop is now three steals shy of tying his career high in the category after logging a steal in back-to-back games. Pena is 12-for-41 (.293) with a homer, two doubles and a triple during August.

Meidroth (thumb) hit off a pitching machine prior to Tuesday's game against the Tigers, MLB.com reports.

Meidroth landed on the injured list Thursday but had been sidelined by the injury since early August. He is reportedly feeling better and has begun to ramp up his activity as a result. Meidroth is eligible to be activated Aug. 15, which looks to be a realistic possibility.

Volpe went 1-for-4 with a three-run home run and a walk in Tuesday's 9-1 win over the Twins.

The speedy shortstop belted his 18th homer of the year, and he tallied at least three RBI for the seventh time in 2025. While Volpe has a middling .708 OPS for the campaign, he remains well within striking distance of a 20-20 season. Over his last 133 at-bats (36 games), he's slugging .436 with 13 extra-base hits, 21 RBI and six stolen bases despite a .195 batting average.

Walls (groin) was placed on the 10-day injured list Tuesday.

Walls has been sidelined with a left groin strain since Saturday, and he will now be forced to spend time on the IL. Outfielder Tristan Peters was called up from Triple-A Durham to replace Walls on the major-league roster.

Wilson (forearm) resumed a hitting progression Tuesday, Jessica Kleinschmidt of Baseball America reports.

Wilson has been prevented from hitting since suffering a left forearm fracture in late July, but it appears he's now been cleared for full baseball activities. Assuming the 23-year-old avoids any setbacks as he continues to ramp up his rehab work, he could be back with the A's within the next week or two.
