Sirota is sporting a .319/.475/.562 slash line with 14 home runs, 11 stolen bases and a 74:79 BB:K over 77 games between High-A Great Lakes and Double-A Tulsa this season.

Sirota's 2025 campaign was interrupted by a knee injury that sidelined him for nearly three months, but he's shown no ill effects in 2026 as he continues to emerge as one of the best position player prospects in baseball. The 23-year-old has split time between center field and right field this season and could find himself at Triple-A Oklahoma City before the end of the summer.

Kilby (hamstring) began a rehab assignment in the Florida Complex League on Friday and went 0-for-1 with a walk and a run scored, Conor Foley of YES Network reports.

It was Kilby's first game action since May 28. The 19-year-old shortstop has been limited to just two contests this season and has yet to see any action with Single-A Tampa, the level he began his pro career at last year. Kilby slashed .353/.457/.441 with two doubles, two triples, nine RBI, 19 runs scored, 16 stolen bases and a 13:11 BB:K across 81 plate appearances after being the 39th pick in the 2025 First-Year Player Draft.

Lux (shoulder) was pulled off his rehab assignment earlier this week, Marc Topkin of the Tampa Bay Times reports.

Lux has appeared in seven games with Triple-A Durham, going 7-for-24 with zero extra-base hits, two RBI and three runs scored. The 28-year-old has yet to play in a big-league game this season due to recurring shoulder issues.

Perdomo received a cortisone injection in his left hand during the All-Star break this week, Alex D'Agostino of SI.com reports.

The issue arose during last week's series in San Diego, manager Torey Lovullo said Thursday. "He battles hand issues throughout the course of the year, ever since we've had him," Lovullo said. "I was told it's not going to hinder him whatsoever." Perdomo posted an image on social media showing his left hand bandaged up. It's unclear if he'll be in the lineup for Friday's series opener against the Cardinals.

The Mets designated Short for assignment Thursday.

Short was selected to the active roster Friday to provide some extra infield depth during the final weekend before the All-Star break, but he'll now lose his spot to make room for Marcus Semien's (hip) return from the IL. Short went 0-for-6 with a walk during his three-game stint with the Mets and is likely to spend most of the second half working as organizational depth in the minor leagues.

Walcott (elbow) began a rehab assignment at the rookie-level Arizona Complex League on Tuesday and has gone 3-for-6 with one home run and one stolen base.

Working his way back from internal brace surgery on his right elbow, Walcott has been used in the designated-hitter spot in his first two rehab games. He's been playing catch, but it's not clear when he will be ready to play the field in games. Walcott finished the 2025 season at Double-A Frisco and will either return to that level or move up to Triple-A Round Rock as his rehab advances.

Nimmala (hamstring) went 3-for-11 with two home runs, three walks, five runs and four RBI in four games for Double-A New Hampshire after being activated from the 7-day injured list July 7.

Nimmala spent five weeks on the shelf while recovering from a hamstring strain before getting the green light to rejoin New Hampshire following a six-game rehab stint between the rookie-level Florida Complex League and Single-A Dunedin. The shortstop prospect has maintained a .303/.398/.434 slash line to go with two home runs and three steals in 22 games for New Hampshire since being promoted from High-A Vancouver on May 3.

Lux (shoulder) went 1-for-4 with two RBI, a walk and a stolen base in a rehab game for Triple-A Durham on Sunday.

Since resuming his rehab assignment June 30, Lux has gone 7-for-24 with five walks, two steals and three runs scored over seven outings. The 28-year-old has been bitten by the injury bug on several occasions this year, first dealing with a right shoulder injury in the spring, next spraining his ankle during an April 11 rehab contest and then getting shut down May 12 due to left shoulder inflammation. Once Lux is finally ready to make his Rays debut, he'll likely be competing with Richie Palacios for reps at second base and Taylor Walls at shortstop.

The Astros promoted Neyens from Single-A Fayetteville to High-A Asheville on Monday, Chandler Rome of The Athletic reports.

Neyens will begin the second half of the season with the Astros' South Atlantic League affiliate after opening his professional career in impressive fashion at Fayetteville. The No. 21 overall pick in the 2025 First-Year Player Draft, Neyens totaled 14 home runs and 16 stolen bases while slashing .240/.449/.462 with a 25.9 percent walk rate and 30.2 percent strikeout rate across 305 plate appearances in the Carolina League.

Atlanta announced Monday that Kim (finger) will begin a rehab assignment in the rookie-level Florida Complex League.

Kim landed on the 10-day injured list July 4 after experiencing inflammation in his surgically repaired right middle finger, but he doesn't look like he'll be in store for a lengthy shutdown. He'll likely play at least a couple games in the FCL early this week before Atlanta decides whether to activate him ahead of its next game Friday versus the Rangers or have him continue his rehab assignment with a higher-level affiliate. After returning from a season-opening stint on the shelf and debuting for Atlanta on May 12, Kim produced a lowly .068/.171/.068 slash line over 82 plate appearances before landing back on the shelf. He'll likely have to settle for a reserve role in the middle infield once he's reinstated.
