Quintana (10-5) took the loss Thursday against the Diamondbacks, allowing six runs on five hits and four walks across 3.2 innings. He struck out two.

It was a tough outing for the veteran left-hander, whose four walks matched a season high. Coming into the day, Quintana had not allowed more than three earned runs in any of his last six starts, posting a 2.94 ERA in that span (33.2 innings). Overall, his ERA sits at 3.96 through 21 starts (114.2 innings) this season with a 1.29 WHIP and 77:43 K:BB. Quintana will look to bounce back his next time out, which is currently slated for next week at home against the Phillies.

Mikolas didn't factor into the decision Thursday against the Pirates, allowing one run on four hits and one walk in five innings. He struck out five.

Thursday marked Mikolas' first start of one or zero earned runs allowed since July 25 against the Padres, and the five strikeouts were his most since July 30 versus the Marlins. It was an especially encouraging rebound performance as well, considering the veteran right-hander matched a season low with 2.2 innings his last time out in Tampa Bay. Mikolas likely benefited from a favorable spot at home Thursday against the last-place Pirates, but he could have a tougher time next week against an Athletics team with a .796 OPS since the beginning of August. For the year, he has a 5.04 ERA, 1.35 WHIP and 86:32 K:BB through 130.1 frames.

Freeland didn't factor into the decision Thursday against the Astros, allowing three runs on eight hits and no walks in six innings. He struck out six.

The quality start was Freeland's 11th of the season, and he also fanned at least six for the fifth time this year. It was also the veteran southpaw's first outing with no free passes since July 30 in Cleveland. Freeland's next appearance is slated for next week at hitter-friendly Coors Field against the division-rival Giants, which means fantasy managers might want to search elsewhere for potential streaming options. Through his 11 appearances at home in 2025, Freeland has a miserable 6.36 ERA, 1.85 WHIP and 41:18 K:BB.

Montas will undergo surgery to repair a torn UCL in his right elbow, Jon Heyman of the New York Post reports.

Whether Montas requires Tommy John surgery might not be known until he has the operation, but a full UCL reconstruction is considered "very likely," per Heyman, which would knock Montas out until the 2027 season. The 32-year-old holds a $17 million player option for 2026 that he'll undoubtedly exercise.

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.

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.

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.

Ritchie gave up one hit and two walks over six scoreless innings for Triple-A Gwinnett on Wednesday. He struck out 11.

The 11 Ks were a career high for the 22-year-old right-hander at any level. Ritchie has made an impressive return from May 2023 Tommy John surgery, beginning the season at High-A and now sitting one promotion away from his big-league debut. Over seven starts for Gwinnett, he's posted a 3.62 ERA, 1.05 WHIP and 39:16 K:BB through 37.1 innings, and while Atlanta has little reason to bring him up in September, Ritchie could get an audition for a rotation spot next spring.

Burns (elbow) is scheduled to throw a bullpen session Saturday, MLB.com reports.

Burns threw a bullpen session without any issues Tuesday and is working his way back to active status. Per the report, an estimated timeline indicates he could possibly return by the end of the season.
