Diaz earned the save against the Cardinals on Tuesday, walking one and striking out one in a scoreless ninth inning.

Diaz was called upon to protect a 4-1 lead in the ninth and tallied his 24th save of the year on 18 pitches. The 27-year-old has nailed down 17 consecutive save chances and owns a 4.07 ERA, 1.38 WHIP and 41:26 K:BB across 42 innings this season.

Minter is slated to see a specialist this week regarding his injured left hip, David O'Brien of The Athletic reports.

Minter landed on the injured list Monday with left hip inflammation -- the second time his hip has forced him to spend time on the IL this year. His first injury caused him to sit out the entire month of June, and Atlanta will know more the southpaw's status for the remainder of the season after his doctor visit.

Wesneski (forearm) threw a 25-pitch bullpen session Tuesday, Maddie Lee of the Chicago Sun-Times reports.

Wesneski has been rehabbing his strained right forearm at the Cubs' facility in Arizona, and Tuesday's workout marked his first mound activity since being placed on the injured list July 20. The 26-year-old appears to be multiple weeks out from being reinstated from the IL.

The Nationals designated Weems for assignment Tuesday, Jessica Camerato of MLB.com reports.

The transaction frees up space on the 40-man roster. Weems has struggled mightily this season, collecting a 6.70 ERA and 35:24 K:BB across 41.2 relief innings.

The Phillies optioned Marte to Triple-A Lehigh Valley on Tuesday.

The right-hander was recalled by Philadelphia on July 20 and will return to the minors after he surrendered seven runs across two-thirds of an inning Saturday at Arizona. Even prior to that ugly showing, Marte had a 4.63 ERA, 1.67 WHIP and 21:13 K:BB across 23.1 big-league innings this season.

Kopech earned a hold against the Brewers on Monday, walking one batter and striking out two in a scoreless inning.

Kopech handled the eighth frame and worked around a two-out walk to keep Milwaukee off the scoreboard. He earned his fourth hold in six appearances since joining the Dodgers on July 29. Kopech has yet to allow a run over 6.1 innings with his new team, and he's surrendered just one hit while posting a 10:1 K:BB. The righty reliever has quickly become Los Angeles' top setup man, but it's unclear if he'll get any save opportunities after working as the White Sox's closer for most of the season prior to being dealt.

Rogers (1-4) allowed an unearned run on one hit and struck out one over one inning, taking the extra-inning loss Monday versus Atlanta.

Rogers gave up the lone run of the game on a sacrifice fly in the 10th inning. He's been fairly steady since the start of July, posting a 2.63 ERA over 13.2 innings in that span, just a touch worse than his 2.25 ERA for the year. He's added a 1.19 WHIP, 56:15 K:BB and five holds over 48 innings overall. While the Giants' bullpen has been restructured after Camilo Doval was demoted to Triple-A last week, Rogers is still unlikely to see much high-leverage work, with Ryan Walker just named the closer and Tyler Rogers and Jordan Hicks slotting in as the preferred setup men.

Atlanta recalled Herget from Triple-A Gwinnett on Tuesday.

The right-hander was optioned to Triple-A in late July but will rejoin the big club ahead of Tuesday's contest in San Francisco. Herget has made six appearances in the majors this season and has a 4.82 ERA, 1.29 WHIP and 10:3 K:BB across 9.1 innings.

Atlanta optioned Logue to Triple-A Gwinnett on Tuesday.

Logue was with the big club for a few days but didn't make an appearance. His spot in the bullpen will be taken by Jimmy Herget, who was called up from Gwinnett.

Iglesias (2-1) picked up the win over the Giants on Monday, striking out four batters over two perfect innings in a 1-0 victory.

Chris Sale and Blake Snell put on a pitching clinic, striking out a combined 23 batters while allowing only five hits and zero runs between them, and the scoreless tie continued into the 10th inning before Atlanta managed to squeeze out a run on a Travis d'Arnaud sacrifice fly. Iglesias, who had entered the game in the ninth, then remained on the mound for the bottom of the 10th and nailed down the win. The veteran closer hasn't allowed an earned run since June 16, posting a minuscule 0.32 WHIP and dazzling 25:2 K:BB over his last 19 innings while collecting both his wins on the season and converting all six of his save chances.
