The Diamondbacks reinstated Jameson from the 15-day injured list Sunday.

The right-hander has been sidelined just over a month due to hip inflammation, but he's ready to rejoin Arizona's bullpen after two minor-league rehab appearances. Jameson has made 11 appearances for the Diamondbacks this year and has a 4.67 ERA, 1.44 WHIP and 13:9 K:BB across 17.1 innings.

O'Brien (3-5) took the loss Sunday against the Phillies, allowing six runs on five hits and a walk over two-thirds of an inning.

O'Brien was called in for a non-save situation to protect a 4-0 lead in the ninth inning, but five straight Phillies reached safely with two outs, including a Kyle Schwarber two-run homer that stuck the Cardinals closer with a brutal loss. Coming into Sunday, the 31-year-old O'Brien had turned in 12 straight scoreless appearances, holding opponents to just two hits over 11.1 innings in that span. He's converted 33 saves this season while posting a 3.93 ERA, 1.22 WHIP and 53:23 K:BB across 52.2 innings.

The Pirates optioned Kelly to Triple-A Indianapolis on Sunday.

Kelly's stint in the big leagues lasted just five days, with the right-hander tossing a scoreless inning in relief during his lone appearance in Saturday's 4-3 loss to the Dodgers. The Pirates called up right-hander Khristian Curtis from Triple-A to replace Kelly in the bullpen.

The Pirates recalled Curtis from Triple-A Indianapolis on Sunday.

Curtis will join the big club for the second time this season and will provide the Pirates with a right-handed relief option who's capable of covering multiple innings. In his lone appearance during his previous stint with the Pirates back in July, Curtis struck out four batters over five scoreless innings of long relief.

Cousins (elbow) faced live hitters Saturday, Fabian Ardaya of The Athletic reports.

Cousins is in the final stages of his recovery from Tommy John surgery, which he underwent last June. The veteran reliever was signed by the Dodgers in late March. Cousins' ability to face live hitters is a sign of progress, but he'll presumably need to log multiple rehab appearances before he's ready to make his Dodgers debut. It's not out of the question that he could be activated before the end of the regular season.

The Tigers optioned De Jesus to Triple-A Toledo on Sunday.

De Jesus has been a decent bullpen option for Detroit this year with a 3.83 ERA, 1.25 WHIP and 39:15 K:BB across 42.1 innings, though he's been a bit shakier over his past six outings with four earned runs allowed. Andrew Sears will take his spot in the bullpen and is poised to work in bulk relief Sunday against the Royals.

Hentges (1-6) took the loss and was charged with a blown save Saturday against the Red Sox, allowing two earned runs on two hits and an intentional walk across one-third of an inning. He also hit a batter.

Hentges entered in the ninth inning with a runner on first base and plunked the first batter he faced. The 30-year-old southpaw went on to give up a single and a double before Boston won on a fielder's choice. Hentges owns a 3.56 ERA, 1.71 WHIP and 33:23 K:BB across 30.1 innings this season.

The Marlins recalled Ralston from Triple-A Jacksonville on Sunday.

The right-hander was added to Miami's 40-man roster in early August, and he's now on the cusp of making his major-league debut. Ralston has enjoyed a strong season for the Jumbo Shrimp with a 2.04 ERA, 1.06 WHIP and 76:30 K:BB across 61.2 innings out of the bullpen.

The Rays reinstated Rodriguez (elbow) from the 60-day injured list Sunday.

Tampa Bay cleared room on the 40-man roster and 26-man active roster for Rodriguez by designating right-hander Chris Roycroft for assignment. Rodriguez served as a high-leverage relief arm for the Rays to begin the 2025 campaign and compiled a 2.08 ERA and 1.05 WHIP while collecting 11 holds over 30.1 innings, but his season came to an early end when he required right flexor tendon repair surgery on Aug. 8. Now just over a year removed from the procedure, Rodriguez has been cleared to rejoin the Tampa Bay bullpen after he completed a month-long rehab assignment during which he submitted a 5.63 ERA, 1.38 WHIP and 14:2 K:BB in eight innings over stops with three different minor-league affiliates. He'll likely be deployed in the middle innings initially, but Rodriguez could quickly work his way up the bullpen pecking order if he looks sharp in his first few appearances with Tampa Bay.

Kimbrel picked up the save Saturday against the Tigers. He allowed no hits and a walk while striking out two over a scoreless inning.

Kimbrel entered the ninth inning with a two-run cushion and retired the side on 20 pitches (14 strikes) to secure his first save of the campaign. The veteran right-hander has yet to allow a run across 5.1 frames since joining Kansas City. Overall, he owns a 4.15 ERA, 1.23 WHIP and 35:18 K:BB across 39 innings between the Royals, Rays and Mets this season. The closer role has been a revolving door in the absence of Carlos Estevez (shoulder), and Kimbrel could see more save opportunities alongside Nate Pearson and Steven Cruz if he keeps delivering.
