The Mets transferred Montas (elbow) from the 15-day injured list to the 60-day IL on Monday.

The transaction clears a spot on the 40-man roster for left-hander Jose Castillo, who was called up from Triple-A Syracuse. Montas has already been ruled out for the season with an injured UCL in his right elbow that could require Tommy John surgery.

Whisenhunt is slated to start Wednesday's game against the Cubs at Oracle Park.

Optioned to Triple-A Sacramento on Aug. 12 after turning in a 5.02 ERA, 1.40 WHIP and 12:7 K:BB in 14.1 innings through his first three MLB starts, Whisenhunt received a call back to the Giants less than two weeks later when an injury to Landen Roupp (knee) reopened a spot in the rotation. Whisenhunt took the hill Friday in Milwaukee and kept the Brewers off the board through the first three frames, but he struggled in his second turn through the batting order and was ultimately tagged for two earned runs on four hits, two walks and one hit batsman across four innings before being lifted from the contest. Despite Whisenhunt's poor numbers in the big leagues to date, he'll receive at least one more start while the Giants are short on quality alternatives at Triple-A to replace him in the rotation.

The Orioles confirmed that Bradish (elbow) will be activated from the 60-day injured list to start Tuesday's against the Red Sox at Camden Yards, Jake Rill of MLB.com reports.

As anticipated, Bradish will slot back into the Baltimore rotation this week to make his first appearance for the big club since June 14, 2024, which came less than a week before he required Tommy John surgery with an internal brace. After a lengthy recovery and buildup process, the righty was cleared to begin a rehab assignment shortly after the All-Star break, and though he produced underwhelming numbers overall across his six starts in the minors (4.91 ERA, 1.41 WHIP in 22 innings), he was sharper over his final two appearances at Triple-A Norfolk (2.79 ERA, 1.24 WHIP, 12:4 K:BB in 9.2 innings). Bradish tossed 89 pitches in his most recent outing with Norfolk this past Wednesday, so he shouldn't be operating with much of a workload restriction in his 2025 debut for Baltimore.

Gusto is listed as the Marlins' probable starting pitcher for Wednesday's game against Atlanta in Miami.

Gusto got the call back to the big leagues Friday when a spot in the Miami rotation opened up, but the right-hander floundered in his start against the Blue Jays, covering six innings but allowing five earned runs on seven hits and one walk while failing to strike out a batter. Despite the poor showing, Gusto will receive another turn through the rotation, but he'll be a prime candidate to move to the bullpen or head back to Triple-A Jacksonville once Ryan Weathers (lat) is reinstated from the 60-day injured list at some point in September.

Tong could be a candidate to receive a call-up from Triple-A Syracuse to start Friday against the Marlins if the Mets elect to expand their rotation to six men, Tim Britton of The Athletic reports.

Tong didn't get promoted to Triple-A until earlier this month, but in his first two starts at the level, he's fired 11.2 shutout innings while striking out 17 and allowing three walks. He leads all minor-league pitchers with 179 punchouts over 113.2 innings on the season and has done everything he can to prove he's ready for a look in the majors. With the Mets in a tight playoff race, the 22-year-old right-hander could provide the boost the team needs to get across the finish line. If the Mets opt not to call up Tong, the team could activate the rehabbing Tylor Megill (elbow) from the 60-day injured list to start Friday, which would buy an extra day of rest for David Peterson and Kodai Senga.

Royals manager Matt Quatraro said that Ragans (shoulder) threw an "up-down" bullpen session Sunday, MLB.com reports.

Ragans is making steady progress in his recovery from a left rotator cuff strain, having now completed five bullpen sessions. Quatraro noted that the southpaw has been feeling good throughout the process, and Ragans' next step in his rehab will be facing live hitters. Ragans has been on the shelf since mid-June, but the Royals remain optimistic that the 27-year-old can return to the rotation before the end of the season.

Megill (elbow) could be activated from the 60-day injured list to start Friday's game against the Marlins at Citi Field, Tim Britton of The Athletic reports.

The Mets will likely want to add a sixth starter this coming Friday in order to buy an extra day of rest for David Peterson and Kodai Senga, and while prospects Brandon Sproat and Jonah Tong are also call-up candidates, Megill might make the most sense after an impressive effort during the third start of his rehab assignment this past Friday with Triple-A Syracuse. In the outing, Megill allowed just one hit and one walk while striking out four and firing 39 of 65 pitches for strikes. If he does get activated to start Friday, it's not clear if Megill will remain in the rotation beyond that outing, asNolan McLean has pitched well in his first two big-league stats to make a case for a permanent stay with the Mets. Over 68.1 innings this season before being sidelined by an elbow sprain in mid-June, Megill compiled a 3.95 ERA, 1.36 WHIP and 89:33 K:BB.

Estes allowed a hit and no walks with a strikeout over four scoreless innings in Sunday's 11-4 loss to the Mariners.

Estes was called on to eat innings in Sunday's blowout loss and delivered four scoreless frames out of the bullpen. It marked his first big-league appearance since April 6, when he opened the year in the rotation and gave up 12 earned runs over seven innings across two starts. With the Athletics' rotation dealing with injuries, Estes could play his way back into a starting role before season's end.

Reds manager Terry Francona said Sunday that Lowder (oblique) could return from the 60-day injured list before the end of the season, Charlie Goldsmith of Fox 19 Now Cincinnati reports.

Lowder has been shelved all season, first with a forearm injury and then with a severe oblique strain, but he's been throwing off a mound and is scheduled for two more bullpen sessions Tuesday and Friday before the Reds map out the next steps in his recovery. Francona suggested Sunday that the most important thing for Lowder is to enter the offseason knowing he's healthy, but the young righty still has a chance to help the big club late in the campaign.

Reds manager Terry Francona said that Burns (elbow) is scheduled to throw a bullpen session Tuesday, Charlie Goldsmith of Fox 19 Now Cincinnati reports.

Burns will throw off the mound for the first time since he was placed on the 15-day injured list Aug. 15 due to a Grade 1 right flexor strain. The rookie lacks a clear timeline to return from the IL, but the Reds could accelerate his activation if they elect to bring him back as a reliever.
