San Francisco acquired Molina from Atlanta on Sunday in exchange for right-hander Tyler Mahle, Ken Rosenthal of The Athletic reports.

Molina has appeared in three games out of the Atlanta bullpen this season, surrendering three runs on six hits and one walk while striking out two batters over five innings. The right-hander worked as a starter in nine of his 18 appearances at Triple-A Gwinnett, but he had been serving as a reliever following his demotion to the minors July 4 and submitted a 1.04 ERA, 0.81 WHIP and 9:2 K:BB in 8.2 innings over his last five appearances. Molina will likely report to Triple-A Sacramento with his new organization but should find his way into the San Francisco bullpen at some point before the end of the season.

Hart did not factor into the decision Sunday, allowing a hit and no walks over three scoreless innings against the Giants. He struck out two.

Tabbed as Sunday's opener after Michael King's start was pushed to Monday, Hart completed a season-high three scoreless innings. The lanky left-hander hasn't allowed a run over his past five outings spanning 9.2 innings, surrendering just five hits while posting a 10:2 K:BB during that stretch. Overall, Hart owns a 4.53 ERA, 1.05 WHIP and 38:13 K:BB across 43.2 innings (29 appearances).

The Mets released Gerber on Sunday.

After designating Gerber for assignment Sunday, the Mets opted to grant him his release rather than waiting for him to first clear waivers. Prior to being demoted to Triple-A Syracuse on July 5, the 29-year-old righty made seven appearances out of the New York bullpen this season, giving up four earned runs on six hits and four walks over 8.1 innings in seven appearances.

Morgan (knee) made a rehab appearance Sunday at Triple-A El Paso, allowing one hit and no walks over an inning of relief.

Morgan kicked off a rehab assignment in the rookie-level Arizona Complex League over the All-Star break, but he made just one appearance before being shut down due to soreness in his right trapezius muscle. The right-hander was able to move past the setback quickly and will likely need just a couple more appearances in the minors before he's deemed ready to rejoin the San Diego bullpen. Morgan submitted a 4.50 ERA and 1.77 WHIP over 18 appearances for the Padres before landing on the shelf June 29 due to left knee inflammation.

Munoz (5-4) blew the save but picked up the win in Sunday's 7-6 win over Minnesota. He allowed one run on two hits and a walk while striking out two over one inning.

Entering with a one-run lead in the ninth inning, Munoz surrendered a game-tying solo homer, though Seattle's offense came through in the bottom of the frame to earn him the win. Sunday marked the 27-year-old's first blown save since June 7, as he has converted 19 of 25 save opportunities in 2026. Overall, Munoz owns a 3.98 ERA, 1.25 WHIP and 63:17 K:BB across 40.2 innings.

Pivetta (forearm) is slated to make a rehab appearance for Single-A Lake Elsinore on Tuesday.

Pivetta has been on the injured list since April 14 due to a right forearm strain, but he's finally reached the last stage of his lengthy recovery process. He won't be the only rehabbing starter slated to pitch for Lake Elsinore on Tuesday, as Joe Musgrove (elbow) is also on track to either start or pitch in relief behind Pivetta. Given the length of his absence, Pivetta would normally require most of his 30-day window to get fully stretched out for a return to the San Diego rotation, but the Padres will give him the chance to streamline his rehab assignment. According to Jeff Sanders of The San Diego Union-Tribune, Pivetta is expected to be activated from the 60-day IL before Aug. 22, when his stay on the shelf would reach 130 days. Per the terms of the four-year contract Pivetta signed in February 2025, if he's deactivated for 130 consecutive days at any point this season or next, his $14 million player option for 2027 and $18 million player option for 2028 would turn into club options.

Petersen (forearm) struck out two batters and allowed no hits and one walk over a scoreless inning of relief en route to claiming his 18th hold of the season in Sunday's 2-0 win over the Mets.

Petersen suffered an injury scare a week ago when he took a line drive off of his right forearm, but he escaped with little more than a bruise and was deemed ready to pitch after a few days of rest. The righty made his return to the mound in Thursday's series opener and was charged with two earned runs across two-thirds of an inning, but he was much sharper Sunday. His 18 holds lead the Marlins, and he lowered his ERA to 3.13 for the season after tossing the scoreless frame.

Athletics manager Mark Kotsay said Sunday that Barnett will maintain his spot in the rotation during the upcoming week, Jason Burke of Roundtable.io reports.

After coming up from Triple-A Las Vegas on July 22, Barnett entered the rotation last weekend and tossed 3.1 innings of bulk relief in a 2-0 loss to the Twins. He then handled a traditional starting role for his next appearance Thursday, limiting a red-hot Red Sox squad to three runs on four hits and one walk while striking out six over five innings. He's earned himself a more permanent stay in the rotation, even though the Athletics will get J.T. Ginn (finger) back from the 15-day injured list Tuesday. Kotsay confirmed that the Athletics won't be moving to a five-man rotation, so one of Jeffrey Springs, Jack Perkins, Jacob Lopez and Gage Jump would appear to be in line to lose his starting role.

The Nationals transferred Poulin (forearm) from the 15-day injured list to the 60-day IL on Sunday.

Poulin had been on the shelf since July 19 due to a left flexor strain, and his move to the 60-day IL ensures that he'll remain out through Sept. 13. The southpaw's move to the 60-day frees up a spot on the 40-man roster for one of Yovanny Cruz and Jake Bird, two of the four players the Nationals acquired Sunday in the deal that sent Luis Garcia to the Yankees.

The Nationals optioned Cornelio to Triple-A Rochester following Sunday's 4-2 loss to Atlanta.

Cornelio will return to Triple-A after just over a month-long stay in the big leagues. The right-hander posted a 4.63 ERA and 1.80 WHIP with 16 strikeouts over 11.2 innings in eight appearances in his second stint of the season with the Nationals. His demotion will clear a spot in the bullpen for right-hander Yovanny Cruz, who was one of four players the Nationals acquired from the Yankees on Sunday in exchange for first baseman Luis Garcia.
