Mize (adductor) tossed five innings, allowing one run on three hits and a walk while striking out five during his rehab start with Single-A Lakeland on Tuesday, Chris McCosky of The Detroit News reports.

Mize was making what could be his first and last start during his minor-league rehab assignment, notching 36 strikes over 55 total pitches. The right-hander appears to be on track toward being activated from the 15-day injured list when first eligible Sunday in Cleveland.

The Athletics recalled Estes from Triple-A Las Vegas on Tuesday.

Estes has accumulated a 5.95 ERA and 1.49 WHIP in 59 innings (12 starts) at Triple-A this season, but he'll be welcomed back into the majors as the replacement on the active roster for Kade Morris, who was optioned to Las Vegas. Though the demotion of Morris creates a void in the big-league rotation, it's unclear if Estes will be the top choice to fill the open spot. Along with Estes, Mason Barnett is a candidate to join the rotation after striking out seven over four shutout innings of long relief in his most recent appearance Friday in Houston. With an off day on tap Thursday, the Athletics could get by without a fifth starter until next week, so Estes will likely be available out of the bullpen for at least the next couple of games.

The Athletics optioned Morris to Triple-A Las Vegas on Tuesday.

Morris gave up nine earned runs in just four innings during his MLB debut Saturday, and he'll now be sent back down to the minors in favor of Joey Estes. Morris owns a 4.45 ERA and 1.48 WHIP in 60.2 innings at Las Vegas and could rejoin the A's at some point later this summer if he gets back on track with the Aviators.

Kochanowicz will undergo Tommy John surgery, Erica Weston of Bally Sports West reports.

Kochanowicz landed on the injured list Sunday due to right elbow inflammation, and an MRI revealed Tuesday that he suffered a torn UCL. The procedure will bring his season to an early end and force him to miss most, if not all, of the 2027 campaign as well.

The Royals activated Kolek from the family medical emergency list Tuesday.

Kolek was away from the club for a few days while tending to a personal matter, but he's back in time to start Tuesday's contest at home versus the Rangers. The right-hander has logged a 3.32 ERA, 0.97 WHIP and 27:8 K:BB over 38 innings covering six starts for Kansas City this season.

Toronto activated Cease (hamstring) from the 15-day injured list to start Tuesday's game against the Phillies, Keegan Matheson of MLB.com reports.

After landing on the IL with a strained hamstring May 25, Cease will rejoin the Blue Jays' rotation having made one rehab start at Triple-A. Before landing on the IL, the 30-year-old recorded a 3.05 ERA, 1.21 WHIP and 92:26 K:BB in 62 innings. Toronto will send down Adam Macko to Triple-A Buffalo in order to make room for Cease on the active roster.

Bucknam will miss all of 2026 and some of 2027 recovering from elbow surgery, Geoff Pontes of Baseball America reports.

The Jays' fourth-round selection in last year's draft, Bucknam will have to wait until at least next summer to make his pro debut.

The White Sox optioned Sandlin to Triple-A Charlotte on Tuesday.

Sandlin was terrific in his major-league debut last month versus the Twins with six innings of one-run ball, but he yielded 11 runs over 7.1 innings in two appearances since then. His turn as a starting pitcher/bulk reliever will come up this weekend against the Dodgers, and the White Sox have not announced how they plan to fill that vacancy.

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.

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.
