Hamilton left Tuesday's game against the Blue Jays with a possible injury, Bryan Hoch of MLB.com reports.

Hamilton replaced Domingo German after German was ejected from Tuesday's start against Toronto due to the presence of a foreign substance. Hamilton should be considered day-to-day for now.

Castillo was optioned to Triple-A Omaha on Tuesday.

Castillo has been solid as a multi-inning reliever for Kansas City, logging a 2.89 ERA through 9.1 innings over three appearances. In spite of his success, he will return to Omaha and be replaced on the MLB roster by Jackson Kowar.

The Royals recalled Kowar from Triple-A Omaha on Tuesday.

Kowar holds a 7.84 ERA and 2.13 WHIP through 20.2 innings across 13 appearances in Omaha this season. His struggles are nothing new, as he hasn't maintained an ERA below 6.00 at any level since 2021. He has a knack for striking batters out at an above-average rate, but Kowar still holds virtually no fantasy value. Max Castillo was optioned to Omaha in a corresponding move.

Jackson (elbow) moved his rehab assignment to Triple-A Sacramento on Tuesday, Susan Slusser of the San Francisco Chronicle reports.

Jackson threw a scoreless inning in his rehab debut Sunday at Single-A San Jose and should be ready to join the Giants' bullpen once he successfully logs back-to-back outings at Triple-A. The 31-year-old reliever is now more than 13 months removed from Tommy John reconstructive elbow surgery.

The Twins selected De Leon's contract from Triple-A St. Paul on Tuesday, Do-Hyoung Park of MLB.com reports.

De Leon last pitched in the majors in 2021 with the Reds, recording an 8.35 ERA and 1.80 WHIP through 18.1 frames. He's done much better this season in the minors (3.62 ERA, 1.37 WHIP) and will take the place of Jorge Alcala (forearm), who landed on the injured list Tuesday.

Alcala was placed on the 15-day injured list Tuesday with a right forearm extensor muscle strain, Betsy Helfand of the St. Paul Pioneer Press reports.

The 27-year-old reliever holds a 6.46 ERA and 1.37 WHIP through 15.1 innings and will now be forced out of action for at least two weeks. Alcala will be replaced on the active roster by Jose De Leon, who was selected from Triple-A St. Paul on Tuesday.

Mlodzinski, 24, has worked exclusively out of the bullpen this year for Triple-A Indianapolis.

The 6-foot-2 righty was trending toward a swing man role in the majors, and moving to relief could give him a chance for his stuff to tick up enough to expedite his ascent to the big leagues. Mlodzinski, the No. 31 overall pick in 2020, has a 4.50 ERA, 1.44 WHIP and 18 strikeouts in 16 innings through 12 appearances.

The Phillies recalled Uelmen from Triple-A Lehigh Valley on Tuesday.

This is the first call-up of the year for Uelmen, who was sporting a 1.04 ERA through 8.2 innings of relief this season at the Triple-A level. The 26-year-old right-hander will be available out of Philly's bullpen Tuesday night against the Giants.

White Sox manager Pedro Grifol told reporters Tuesday that Hendriks (illness) will make another rehab appearance for Triple-A Charlotte on Thursday, James Fegan of The Athletic reports.

Grifol said the team would then evaluate Hendriks after that outing. Hendriks has struggled in his rehab appearances thus far with an 11.25 ERA over four innings from five appearances. If the right-hander pitches well for the Knights on Thursday, he could be back with Chicago at the end of the week, but the team won't rush Hendriks back, as he is still a little over a month removed from his last round of chemotherapy for non-Hodgkins lymphoma.

Texas optioned Bradford to Triple-A Round Rock on Tuesday.

Bradford made his MLB debut against Atlanta on Monday and the left-hander allowed six runs over five innings while picking up the loss. He could be back up at some point this summer, but it was fully expected the 25-year-old was only making a spot start. Joe Barlow was recalled from Triple-A in a corresponding transaction.
