Chapman collected the save in Monday's 6-4 victory over the Guardians, pitching a clean inning with one strikeout.

The flamethrowing southpaw required only five pitches to pocket his 363rd career save. Chapman has notched 16 consecutive scoreless appearances over which he's fired 12.2 hitless frames with a 16:4 K:BB and 11 saves. The 37-year-old has reentered the discussion as one of the elite fantasy closers this season thanks to his 1.00 ERA, 0.65 WHIP and 77:14 K:BB across 54 total innings.

The Diamondbacks activated Thompson (shoulder) from the 15-day injured list Monday.

Thompson has been shelved since early July with a right scapular strain but is ready to go after making a pair of scoreless rehab appearances with Triple-A Reno. The 33-year-old could be in the mix for saves as part of an unsettled Diamondbacks bullpen.

Gipson-Long will be recalled from Triple-A Toledo to start Tuesday's game against the Mets in Detroit, Evan Woodbery of MLive.com reports.

Gipson-Long holds a 4.32 ERA, 1.04 WHIP and 20:4 K:BB in 25 innings covering two starts and four relief appearances for the Tigers this season. He hasn't reached the five-inning mark in an appearance since late June, so the right-hander could be in line for a relatively abbreviated outing Tuesday. Gipson-Long seems likely to be shifted to long relief after Tuesday's spot start, if he isn't optioned back to Triple-A.

The Padres recalled Reynolds from Triple-A El Paso on Monday.

Reynolds has appeared in 18 games for San Diego this season and owns a 5.55 ERA, 1.32 WHIP and 22:13 K:BB across 24.1 innings. He'll likely handle a low-leverage relief role during his upcoming stint with the Padres.

Poteet elected to free agency Monday, Jake Rill of MLB.com reports.

Poteet has decided to hit the free-agent market rather than accepting the Orioles' outright assignment to Triple-A Norfolk. The 31-year-old has missed much of the season with a shoulder injury but recently turned in two scoreless outings at Norfolk.

The Dodgers activated Kopech (knee) from the 60-day injured list Monday.

Kopech had surgery July 1 to repair a torn meniscus in his right knee, but he's ready to join the big-league bullpen after making seven rehab appearances with Triple-A Oklahoma City. The righty held an 11.81 ERA and 5:9 K:BB over 5.1 innings in those outings, so the Dodgers are likely to ease Kopech into high-leverage spots.

The Rays recalled Kelly from Triple-A Durham on Monday.

Kelly holds an unsightly 5.93 ERA and 1.57 WHIP through 27.1 innings with the Rays this season. He'll give the club another relief arm for the final month of the campaign.

The Orioles activated Suarez (shoulder) from the 60-day injured list Monday.

Suarez hasn't pitched in the big leagues since suffering a shoulder strain in his first appearance of the season back on March 28. He made five rehab appearances, registering a 3.55 ERA, 1.18 WHIP and 5:6 K:BB across 12.2 innings of work. Now healthy again, Suarez is expected to work as a long-relief option for Baltimore.

Brewers manager Pat Murphy said that Megill (elbow) has been playing catch and has a bullpen session scheduled for Thursday, Adam McCalvy of MLB.com reports.

Megill landed on the 15-day injured list last Wednesday with a Grade 1 right flexor strain, but he's aiming for a minimum-length stay on the IL and appears to be tracking toward achieving that goal. The reliever will be eligible for activation Sept. 9. Abner Uribe has been filling in as the Brewers' closer since Megill was placed on the shelf.

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

Rodriguez needs Tommy John surgery and is expected to remain out through the end of the 2026 season. The All-Star reliever was electric out of the San Francisco bullpen this season, posting a 1.78 ERA, 0.89 WHIP and 67:11 K:BB across 50.2 innings. Rodriguez took over as the Giants' closer following the trade of Camilo Doval to the Yankees in late July, but Ryan Walker looks poised to see most of the save chances for San Francisco in September.
