The Giants transferred Miller (elbow) from the 15-day injured list to the 60-day injured list Thursday.

Miller experienced a setback with his left elbow injury last week on a rehab assignment. He would be eligible for activation from the IL in early September, but the lefty will not resume throwing for another couple weeks, so his season might very well be over.

The Reds optioned Mey to Triple-A Louisville on Thursday, Gordon Wittenmyer of The Cincinnati Enquirer reports.

Mey has managed to hold the opposition to one run over 6.2 innings during his latest stint in the majors, but that's in spite of nine hits and seven walks. The Reds will announce a corresponding roster move prior to Friday's game in Arizona.

The Dodgers recalled Sauer from Triple-A Oklahoma City on Thursday.

Sauer holds a 6.18 ERA and 22:8 K:BB over 27.2 innings covering one start and eight relief outings for the Dodgers this season. He'll give manager Dave Roberts a fresh arm after the bullpen covered four frames in Wednesday's loss to the Rockies.

The Dodgers optioned Gervase to Triple-A Oklahoma City on Thursday.

Gervase was recalled Wednesday and was put to work in the team's loss to the Rockies later that night, allowing one run over a two-inning relief appearance. He'll give up his spot on the active roster and in the bullpen to Matt Sauer, who was recalled from Triple-A ahead of Thursday's series finale in Colorado.

Iglesias struck out one in a perfect ninth inning Wednesday to record his 21st save of the season in a 1-0 win over the White Sox.

All eight of Iglesias' pitches found the strike zone in a ruthless performance from the veteran closer. The right-hander held a 6.75 ERA as late as June 5, but since then Iglesias has been one of the best late-inning arms in baseball, posting a 1.52 ERA, 0.61 WHIP and 33:4 K:BB over his last 29.2 innings while converting 13 of 14 save chances.

Halvorsen (elbow) is continuing his rehab, but he will not begin the next steps toward his return to the field until early September, MLB.com reports.

The Rockies continue to say that Halvorsen could return this season, but it appears that he will only be available for a few weeks at best. His role upon his return could also be murky, as Victor Vodnik has turned in five consecutive scoreless appearances, piling up four saves and a win.

Waldrep (4-0) picked up the win Wednesday, allowing four hits and a walk over seven scoreless innings in a 1-0 victory over the White Sox. He struck out seven.

The rookie right-hander was impressive once again, firing 60 of 87 pitches for strikes as he tied his career high in Ks. Waldrep has won all four of his starts since being brought up at the beginning of August, producing a stellar 0.73 ERA, 0.77 WHIP and 24:6 K:BB over 24.2 innings. The 2023 first-round pick will look to keep rolling in his next outing, which is scheduled to come on the road early next week in Miami.

Crismatt is slated to start Saturday's game against the Reds at Chase Field.

A journeyman reliever for most of his first six seasons in the big leagues, Crismatt had been getting stretched out in the Triple-A Reno rotation before the Diamondbacks called him up this past Sunday to make his second career MLB start. The 30-year-old righty was unfazed by the harsh pitching conditions at Coors Field, taking a no-decision and striking out five batters over five innings while limiting the Rockies to one run on three hits and one walk. He'll return to a slightly more forgiving pitching environment in Arizona for his second turn through the rotation, though Crismatt's lack of a track record as a starter in the big leagues will make him difficult to trust as a streaming option until he strings together a few more promising appearances.

Morgan (elbow) tossed a perfect inning in his first rehab appearance with High-A South Bend on Wednesday.

Morgan initially went down with a right elbow impingement in mid-April and then suffered a setback while on his initial rehab assignment in mid-June. He's now getting back on track and could rejoin the Cubs' bullpen around Sept. 1 if all goes well.

Ferrer gave up a hit in a scoreless ninth inning Wednesday to record his third save of the season in a 5-4 win over the Mets.

The southpaw was able to erase a one-out single by Cedric Mullins with a game-ending double play thanks to a 97.9 mph sinker. Ferrer has pocketed three of the Nationals' four saves in August, with Cole Henry notching the fourth, and the former is the clear top option for closing duties in the bullpen. Over 17.1 innings since the beginning of July, Ferrer has posted a 2.08 ERA, 1.21 WHIP and 15:2 K:BB.
