The Angels optioned Kochanowicz to Triple-A Salt Lake on Thursday.

The transaction comes one day after Kochanowicz was pummeled for 11 runs (10 earned) over 3.1 innings in a loss to the Rangers. The Angels will have to fill Kochanowicz's rotation spot next week, with Caden Dana among those likely to be under consideration.

The Marlins recalled Mazur from Triple-A Jacksonville on Thursday.

Mazur will start Thursday's game against the Mets, taking the rotation spot of the injured Janson Junk (elbow). The right-handed Mazur has looked unready for the majors in his nine big-league starts dating back to last season, collecting a 7.32 ERA and 27:25 K:BB over 39.1 innings. Mazur could get at least a couple turns until Junk and/or Ryan Weathers (lat) are ready to rejoin the Marlins' rotation.

Cardinals manager Oliver Marmol said Thursday that Pallante will make his next scheduled start Sunday in Cincinnati, John Denton of MLB.comreports.

Pallante has posted an 8.26 ERA, 1.72 WHIP and 32:17 K:BB over 44.2 innings covering his last nine starts, but the Cardinals believe his underlying metrics point to better success moving forward and want the hurler work through his issues in the big-league rotation. The right-hander should not be used in fantasy leagues until he shows some improvement, particularly with a start at Great American Ball Park looming this weekend.

Astros manager Joe Espada said Thursday that McCullers is available to pitch out of the bullpen, Chandler Rome of The Athletic reports.

Espada described the move as "short-term" and noted that McCullers is an option to start Monday's game against the Angels. Luis Garcia (elbow) is also an option to return from the 60-day injured list start Monday, and the two could be used in tandem if McCullers isn't needed out of the bullpen Thursday versus the Rockies or during the first three games of the series with the Angels over the weekend. In his most recent start this past Friday in Baltimore following his return from the IL, McCullers yielded three runs and walked five over four innings. He's now sitting on a 6.89 ERA in 12 starts this season.

Basso allowed no hits and a walk with no strikeouts over a scoreless inning Wednesday against the Tigers.

Basso made his season debut for the Athletics, tossing a scoreless ninth inning to close out an impressive sweep of the Tigers. The southpaw has spent most of the year sidelined by a left shoulder strain suffered in March, then was optioned to Triple-A Las Vegas upon activation Aug. 11 before being recalled ahead of Wednesday's contest. Though a starter by trade, Basso has been working out of the bullpen since returning from injury.

The Red Sox could promote Tolle from Triple-A Worcester to start or make a bulk-relief appearance in Friday's game against the Pirates, Christopher Smith of MassLive.com reports.

Boston has confirmed that Dustin May will start the second game of the series Saturday, and Lucas Giolito appears on track to start Sunday's series finale, but the club still has an opening in its rotation for Friday after Richard Fitts (arm) was removed from his bulk-relief appearance in Monday's game against the Orioles before landing on the injured list. Kyle Harrison -- who is already on the Red Sox's 40-man roster -- made an abbreviated three-inning start for Worcester on Tuesday to keep him in play for a promotion to the big leagues Friday, but Tolle has established himself as the organization's top pitching prospect this season and may have done enough to make a case for his first MLB call-up. After accruing a 2.93 ERA and racking up 116 punchouts across 76.2 innings through his first 17 outings of the season between High-A Greenville and Double-A Portland, the 22-year-old lefty has continued to shine since moving up to Worcester earlier this month. Through three starts at Triple-A, Tolle has accrued a 3.60 ERA, 0.87 WHIP and 17:2 K:BB in 15 innings.

High-A Greenville reinstated Valera (elbow) from its 60-day injured list Tuesday.

Valera has yet to return to action for Greenville since being activated, but he's apparently healthy again after he was recently able to face hitters in live batting practice. Before being shelved in late May due to right elbow soreness, Valera turned in a 5.40 ERA, 1.42 WHIP and 37:9 K:BB in 33.1 innings over eight starts for Greenville.

The Rockies will activate Marquez (biceps) from the 15-day injured list to start Friday's game against the Cubs at Coors Field, MLB.com reports.

Marquez has been on the shelf since July 23 due to right biceps tendinitis, but he was cleared to rejoin the Colorado rotation after he completed a bullpen session Wednesday without incident. Before linking back up with the Rockies this week, Marquez completed two rehab starts for Triple-A Albuquerque. He most recently pitched for Albuquerque on Sunday, striking out seven and allowing two earned runs on five hits and one walk over 4.1 innings (76 pitches). To make room for Marquez in the rotation, Colorado moved Antonio Senzatela to the bullpen earlier this week.

Yesavage allowed one run on two hits and two walks over 4.2 innings for Triple-A Buffalo on Wednesday. He struck out five.

After a bumpy debut at Triple-A on Aug. 14, the 22-year-old right-hander has a 3.86 ERA, 1.07 WHIP and 13:4 K:BB in 9.1 innings over his last two starts. Yesavage has pitched at four levels in his first pro campaign, and the 2024 first-round pick could make it five if the Blue Jays add him to the big-league bullpen in September.

Caminiti struck out a career-high nine for Single-A Augusta on Wednesday, allowing one run on four hits and two walks over six innings.

In addition to setting a new personal best in Ks, Caminiti completed six innings in a start for the first time. The 2024 first-round pick has found another gear since the All-Star break, posting a 1.61 ERA, 1.25 WHIP and 37:13 K:BB over his last 28 innings, and he could be setting the stage for a rapid rise through the Atlanta system in 2026.
