Diaz (oblique) is starting a minor-league rehab assignment Tuesday, Chandler Rome of The Athletic reports.

The 27-year-old has been on the injured list since early May due to an oblique strain, but he's been cleared for game action after ramping up his baseball activities. Diaz had a poor start to the season offensively with a .602 OPS through 26 games, and Christian Vazquez's superior work behind the plate could mean that the Astros deploy a more even split of playing time at catcher, per Rome.

Single-A Charleston placed Gray on its 7-day injured list June 1 due to an unspecified issue.

Gray's move to the IL temporarily halts what's been a magnificent first season in the professional ranks for the 18-year-old, who has settled in at first base after being listed as a catcher when he was selected in the third round of the 2025 First-Year Player Draft. Prior to hitting the shelf, Gray produced a .286/.406/.474 slash line with a 16.8 percent walk rate and 21.9 percent strikeout rate over 192 plate appearances with Charleston.

The White Sox are slated to call up Montgomery from Triple-A Charlotte, James Fegan of SoxMachine.com reports.

Montgomery began the 2026 season at Double-A Birmingham before being promoted to Charlotte in early May. He's been excellent at both stops, slashing a combined .314/.422/.548 with 10 home runs, five stolen bases and a 39:64 BB:K over 56 contests. Montgomery has some swing-and-miss concerns, but he draws walks and has big power. He's played both center and right field this season in the minors and could be used at either or both positions with the White Sox.

Kolek (personal) is listed as the Royals' probable starter for Tuesday's game against the Rangers in Kansas City.

Kansas City placed Kolek on the family medical emergency leave list Thursday, but the right-hander looks set to rejoin the Royals for the start of their series with the Rangers and won't have to miss a turn through the rotation. The Royals will make his activation official shortly before Tuesday's 7:40 p.m. ET start time.

Clement went 2-for-4 with a solo home run in Monday's loss to the Phillies.

The 30-year-old infielder took Cristopher Sanchez deep in the fifth inning, providing the last bit of offense in a 5-2 loss. Clement has two homers in the last three games and four multi-hit performances in the first seven games of June, boosting his slash line on the season to .309/.328/.473 with seven home runs, two steals, 26 RBI and 31 runs in 66 contests.

High-A Bowling Green placed Brito on its 7-day injured list May 23 due to an unspecified issue.

Brito, a 21-year-old righty, had submitted a 3.34 ERA, 1.55 WHIP and 42:21 K:BB in 32.1 innings over his first eight starts with Bowling Green before landing on the shelf.

Yankees manager Aaron Boone said on the "Talkin' Yanks" podcast by Jomboy Media that Caballero will not be in the lineup for Tuesday's game in Cleveland.

The Yankees will go with Anthony Volpe at shortstop in the second game of the three-game set. Since returning from the injured list in late May, Caballero has started 11 of 15 games (five at shortstop), while Volpe has started 10 of 15 (all at shortstop).

High-A Frederick placed George on its 7-day injured list May 7 due to an undisclosed medical issue, Matt Weyrich of The Baltimore Sun reports.

When he addressed George's situation May 15, Orioles president of baseball operations Mike Elias didn't delve into much detail regarding the matter beyond relaying the 20-year-old outfielder would be "out for a while." A 16th-round draft pick in 2024, George arrived in the professional ranks without much of a pedigree but cemented himself as one of the Orioles' top prospects after producing a .337/.413/.483 slash line with five home runs and 50 steals in 87 games across three levels in 2025. George had gotten off to a nice start to the 2026 campaign prior to being shut down in early May, posting a .372 on-base percentage while notching 15 steals in 17 attempts over 20 games with Frederick.

Hurd (elbow) has allowed 11 runs (10 earned) on 11 hits and five walks while striking out six batters across seven innings since being activated from Single-A Tampa's 7-day injured list May 26.

The No. 89 overall pick in the 2024 First-Year Player Draft, Hurd didn't make his professional debut until just over a month ago after completing his recovery from February 2025 Tommy John surgery. The 23-year-old righty was sharp over three rehab appearances in the rookie-level Florida Complex League (1.59 ERA, 0.97 WHIP and 12:5 K:BB in 11.1 innings), but he was roughed up for 10 runs in just 2.1 innings in his first start for Tampa. Hurd bounced back nicely his last time out for Tampa, however, striking out four and permitting one unearned run across 4.2 frames.

Bieber (elbow) is scheduled to make the fourth start of his rehab assignment Thursday with Triple-A Buffalo, Ben Nicholson-Smith of Sportsnet.ca reports.

After pitching for three different affiliates during his first three rehab outings, Bieber will stick around with Buffalo for a second consecutive appearance. Per Shi Davidi of Sportsnet.ca, Blue Jays manager John Schneider said Monday that Bieber could push up to the 70-75-pitch range Thursday, which would put him in consideration for a 2026 MLB debut as soon as next week. However, the right-hander may realistically need another rehab appearance or two beyond Thursday, given the uneven results he's had as he works his way back from inflammation in his surgically repaired right elbow. While Bieber has posted a strong 8:0 K:BB in seven innings during his time in the minors, he's been knocked around for eight earned runs on 15 hits.
