Mayza (lat) has been completing side sessions at the Pirates' spring training facility, MLB.com reports.

Mayza has been throwing for nearly a month, but this activity marks progress in his rehab. He'll still need to face live hitters and complete a rehab assignment before being activated from the injured list.

Santana (3-3) was the pitcher of record in Friday's 17-16 loss to the Rockies after he retired just one batter and allowed five earned runs on four hits and one walk.

Called upon to protect a four-run lead in the ninth inning, Santana struck out the first batter he faced but then allowed the next five runners to reach while serving up two home runs in the process. Despite the disastrous outing, Santana has been excellent this season, as Friday's outing marked the first time he's allowed multiple earned runs in his last 20 appearances. He should still be projected to earn the majority of save chances after the departure of David Bednar ahead of Thursday's trade deadline, but his effectiveness in the role will be worth monitoring.

Kittredge tossed a scoreless inning of relief with two strikeouts to earn a hold in Friday's 1-0 win over the Orioles.

Kittredge was traded from the Orioles to the Cubs on Wednesday, and he was sharp in his Chicago debut facing his former team. The righty now has eight holds this season to go along with a strong 3.34 ERA, 1.05 WHIP and 34 strikeouts across 32.1 innings. Kittredge won't be closing games for the Cubs, as Daniel Palencia has emerged in that role, but the former will slot in as a valuable setup man along with Caleb Thielbar, Brad Keller, Drew Pomeranz and Taylor Rogers in a revamped Chicago bullpen.

Giants manager Bob Melvin said that Teng will start Saturday's game against the Mets at Citi Field, Susan Slusser of the San Francisco Chronicle reports.

Teng made four appearances out of the San Francisco bullpen in the opening month of the 2024 season, but he had pitched exclusively in the minors ever since then before the Giants called him up from Triple-A Sacramento on Friday. The right-hander had been limited to 1.2 innings in his most recent outing with Sacramento on July 25, but that was largely because the Giants wanted to keep him fresh for a potential start with the big club last week that ended up falling to Carson Whisenhunt. The Giants still had another opening in the rotation with Landen Roupp (elbow) recently landing on the injured list, so Teng will be needed for at least one start. Over 25 appearances (four starts) with Sacramento on the season, the 26-year-old righty owns a 3.67 ERA, 1.11 WHIP and 86:21 K:BB in 54 innings.

DeSclafani (1-2) allowed four runs on five hits and three walks while failing to record a strikeout over 2.1 innings, taking the loss Friday versus the Athletics.

DeSclafani threw 59 pitches (33 strikes) in this outing, one off his season high from July 6 versus the Royals. It was a poor start for the veteran right-hander, as he allowed all four runs in the first inning. DeSclafani is still relatively stretched out after serving as a multi-inning reliever a majority of the time since he signed with Arizona on June 15. He's struggled to a 4.91 ERA, 1.29 WHIP and 24:9 K:BB through 25.2 innings across nine appearances (two starts). It's unclear if he'll be the rest-of-season answer in the rotation following the Diamondbacks' deal that sent Merrill Kelly to the Rangers on Thursday. DeSclafani is tentatively scheduled to make his next start at home versus the Padres.

Miller allowed two hits and struck out one in a scoreless inning to earn a hold in Friday's 4-1 win over the Cardinals.

The Padres' acquisition of Miller came amid a flurry of moves for the team, but Robert Suarez also remained in San Diego. That could lead to the creation of a closer committee. In Friday's contest, Miller was brought in to face the Cardinals' fifth through eighth hitters, while Suarez worked the ninth inning as the order turned over. Miller has youth on his side, but he was a little wild at times with the Athletics, posting a 3.76 ERA and 59:18 K:BB over 38.1 innings prior to the trade. Keep an eye on this bullpen in the coming weeks to see how the ninth-inning duties get divvied up.

Suarez allowed a hit in a scoreless inning to earn the save in Friday's 4-1 win over the Cardinals.

The Padres' bullpen got a massive boost with the addition of Mason Miller at Thursday's trade deadline, but it was still Suarez in the ninth inning -- and against the top of the Cardinals' order -- in Friday's game. Miller worked the eighth inning, allowing two hits in a scoreless frame. Manager Mike Shildt has plenty of high-leverage arms to work with, but it remains to be seen which reliever, if any, will get a clear-cut closer role. Suarez leads the majors with 31 saves and has a 3.35 ERA, 1.01 WHIP and 47:12 K:BB across 45.2 innings this season, but he posted a 4.87 ERA over 20.1 innings in June and July combined, so his stability has potentially taken a hit. Nonetheless, it looks like Suarez is at least in the mix for save chances over the last two months of 2025.

Rodriguez earned the save in Friday's 4-3 extra-inning win over the Mets, recording one walk and one strikeout in a scoreless 10th inning.

Rodriguez was called on to protect a one-run lead in the 10th inning, needing 16 pitches to secure his first save since officially being named the Giants' new closer. The 25-year-old has been one of baseball's top relievers, boasting a 1.17 ERA, 0.85 WHIP and 63:10 K:BB across 46 innings with two saves and 13 holds. He should become even more valuable in his new role moving forward.

Ross (back) made his first rehab appearance with Triple-A Lehigh Valley on Friday, allowing one hit and no walks in a scoreless fourth inning. He struck out two.

Ross was sharp Friday, throwing 10 of his 15 pitches for strikes. The 32-year-old right-hander is rehabbing from back spasms, and he should be able to return to the Phillies in early August if all goes well. Ross will likely operate as a multi-inning middle reliever once he's activated from the injured list.

Wrobleski earned the save in Friday's 5-0 win over the Rays, allowing one hit and no walks in three scoreless innings. He struck out five.

With the Dodgers holding a 5-0 lead, Wrobleski was brought on essentially for mop-up duty and picked up his first save of the year. The left-hander has a 4.00 ERA, 1.13 WHIP and 46:11 K:BB over 45 innings, and he should continue to serve as a multi-inning weapon but still likely isn't a candidate for many more future save chances out of Los Angeles' bullpen.
