Mlodzinski will serve as the Pirates' opening pitcher for Tuesday's game against the Marlins, Andrew Destin of the Pittsburgh Post-Gazette reports.

Mlodzinksi's longest outing since returning from the injured list Aug. 27 has been two innings, so he'll likely work the opening frame or two before handing the ball to a bulk reliever. Joey Wentz could be a candidate to eat up innings after Mlodzinski's work is done.

Diaz pitched a perfect ninth inning Monday to pick up the save against Atlanta. He did not allow a hit or a walk and did not collect a strikeout.

Diaz entered a 1-0 game and kept Atlanta off the bases for his 27th save and third in his last four appearances. Following a rough August where Diaz pitched a 7.00 ERA and blew two saves, Diaz has bounced back in September as he has yet to allow a hit in five appearances in the month. The 27-year-old has been up and down this season but remains one of the more reliable options for saves as he ranks ninth in MLB in that category.

Martinez (8-6) got the win Wednesday against Atlanta, allowing two hits and one walk over seven scoreless innings. He struck out five.

Martinez pitched a gem Monday as he continues to settle into his new role in the rotation. Even though he had started sparingly earlier in the season, Martinez has now received eight straight starts and is pitching to a 3.12 ERA over that span. The 34-year-old veteran threw his fourth career start of seven or more innings without allowing a run, and two of those have come over his last eight starts.

Graterol (hamstring) will likely be activated from the 15-day injured list prior to Wednesday's game against the Cubs, Fabian Ardaya of The Athletic reports.

Graterol has been out since Aug. 7 after suffering a Grade 3 right hamstring strain, but he's expected to be cleared for the team's final game of the series Wednesday if all goes according to plan. It wouldn't be a surprise to see the club deploy the right-hander in a few low-leverage situations upon his return, as he's logged one-third of an inning so far this season dating back to Aug. 6 against Philly.

The Phillies recalled Gilbert from Triple-A Lehigh Valley on Monday.

Gilbert will offer the Phillies some length out of their bullpen after Philadelphia needed three relievers plus backup catcher Garrett Stubbs to cover the final 5.2 innings of Sunday's 10-1 loss to the Marlins. Starter Seth Johnson was optioned to Triple-A after starting Sunday and giving up nine earned runs across 2.1 innings in his MLB debut.

Miller (4-5) allowed a hit and a walk while failing to record a strikeout over 1.2 scoreless innings, earning the win Sunday over the Padres.

Spencer Bivens got the start but couldn't get through five innings. The Giants led 6-1 when Bivens was relieved by Miller, and they were able to hold the lead the rest of the way to give the southpaw reliever his first win since July 9. Since the start of August, Miller has a 4.50 ERA, 1.50 WHIP and 21:11 K:BB over 14 innings. He's at a 3.65 ERA, 1.25 WHIP and 78:34 K:BB with 12 holds over 61.2 innings this season.

Iglesias (5-1) picked up the win Sunday over the Blue Jays, giving up an unearned run on two hits and a walk over two innings of relief. He struck out one.

The Atlanta closer entered a tie game in the top of the 10th inning with a save chance no longer on the table, and while Iglesias allowed the phantom runner to score in the 11th, his offense walked it off in the bottom of that frame. Iglesias hasn't been tagged with an earned run since June 16, and on the season he sports a dazzling 1.18 ERA, 0.66 WHIP and 62:11 K:BB through 61 innings. He's three saves shy of tying his career high of 34, a mark he reached in both 2019 and 2021.

Tinoco has turned in a 1.47 ERA, 0.60 WHIP and 24:4 K:BB while collecting one win and five holds over 18.1 innings across 15 appearances out of the bullpen since the Marlins claimed him off waivers from the Cubs on July 30.

Tabbed to fill one of the openings in the bullpen that was created by the Marlins' fire sale ahead of the trade deadline, Tinoco has arguably performed better with Miami than any of the relievers (Tanner Scott, Bryan Hoeing, A.J. Puk, Huascar Brazoban and JT Chargois) that were dealt away. A 29-year-old journeyman who owns a modest 3.82 ERA over 74 career MLB appearances, Tinoco attributes part of his newfound success in Miami to his increased usage of a slider that he revamped while pitching overseas in Japan in 2023, per Kevin Barral of FishOnFirst.com. Tinoco has quickly moved into a high-leverage role out of the Marlins bullpen, and he could now get a chance to pick up saves down the stretch after incumbent closer Calvin Faucher (shoulder) landed on the injured list Saturday. John McMillon and Anthony Bender loom as potential challengers for closing duties.

Cronin (undisclosed) struck out two batters and collected a hold across two perfect innings of relief in his first two appearances of September on Wednesday and Saturday.

Cronin was lifted during an extended relief appearance Aug. 29 in Colorado due to an apparent injury, but he returned to action just under a week later to remove any lingering concern about his health. The 26-year-old righty has picked up four of his six holds on the season in the past month and could be primed to pitch in more high-leverage situations down the stretch with Calvin Faucher (shoulder) recently joining Andrew Nardi (elbow) on the shelf.

Kinley struck out one batter in a perfect inning and earned a save against Milwaukee on Sunday.

Kinley retired the Brewers' 2-3-4 hitters in order to close out the 4-1 victory. Since coughing up four runs against the Marlins on Aug. 27, he's converted four straight save chances without allowing a run. He's now 11-for-12 in save chances with a 5.98 ERA and a 68:31 K:BB through 61.2 innings, though it's worth noting that teammate Victor Vodnik (biceps), who has nine saves this season, was activated from the 15-day injured list Sunday.
