The Diamondbacks transferred Thompson (back) to the 60-day IL on Tuesday.

Thompson initially landed on the injured list Aug. 5 with a lower-back strain, so his move to the 60-day IL will officially rule him out for the rest of the regular season. Blake Walston (elbow) will return from the 60-day IL in a corresponding move to claim the open spot on Arizona's 40-man roster.

The Rockies recalled Castano from Triple-A Albuquerque on Tuesday.

Castano has logged a 3.92 ERA and 17:6 K:BB across 20.2 innings with the Rockies this season. The 27-year-old is likely to be used as a multi-inning reliever in Colorado.

The Cubs recalled Ferguson from Triple-A Iowa on Tuesday.

Ferguson has put in some quality work for the Cubs this season in posting a 3.45 ERA, 0.77 WHIP and 19:2 K:BB over 15.2 innings. The 32-year-old will likely be used primarily in a middle-relief role.

The Brewers activated Romero (appendectomy) from the 15-day injured list Tuesday.

Romero underwent an appendectomy in mid-July when he was still a member of the Cardinals organization. He's ready for his Brewers debut now after making two scoreless rehab appearances.

The Mets recalled Ross from Triple-A Syracuse on Tuesday.

In 36.1 innings with Syracuse this season, Ross has posted a 6.94 ERA and 45:31 K:BB. The 26-year-old will be making his major-league debut when/if he gets into a game.

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

Holman was a waiver claim of the Phillies back in May and has posted a 3.60 ERA and 28:7 K:BB over 30 innings at the Triple-A level in 2026. He made 40 appearances for the Athletics over the previous two seasons, holding a 4.66 ERA and 33:18 K:BB in 38.2 frames.

The Pirates recalled Eisert from Triple-A Indianapolis on Tuesday.

Eisert will give manager Don Kelly another lefty for the bullpen. The 28-year-old has posted a 6.29 ERA in 34.1 major-league innings this season, but a 40:12 K:BB is more promising.

The Nationals selected Simpson's contract from Triple-A Rochester on Tuesday, Spencer Nusbaum of The Athletic reports.

Simpson has split this season between Double-A Harrisburg and Rochester, logging a 2.30 ERA and 73:38 K:BB over 58.2 innings. The 26-year-old southpaw will be making his major-league debut when/if he enters a game.

The Marlins recalled Blalock from Triple-A Jacksonville on Tuesday.

Blalock was acquired from the Rockies in a trade back in January but has spent all season at Jacksonville, posting a 5.61 ERA and 103:46 K:BB over 109 frames covering 23 starts. The right-hander appears set to be deployed in long relief, though he could wind up making a start or two during the final month.

The Padres recalled Brito from Triple-A El Paso on Tuesday.

It will be the third look in the majors this year for Brito, who has made three relief appearances for the Friars and given up two earned runs with a 4:1 K:BB over 5.1 innings. The right-hander could provide some length given that he's worked out of the rotation at Triple-A, where he has a 2.98 ERA, 1.26 WHIP and 27:9 K:BB across 42.1 innings this year.
