Dodgers manager Dave Roberts said Monday that Diaz (neck) "hasn't been good" on his rehab assignment and "needs to pitch better" before the team considers returning him to the active roster, Sonja Chen of MLB.com reports.

Diaz gave up five runs on two hits and three walks while recording only two outs in his last rehab appearance with Triple-A Oklahoma City on Sunday, and he's allowed six runs with a 4:7 K:BB in 3.1 rehab innings. Diaz has been out since mid-August with neck inflammation, and while his health no longer is a concern, the Dodgers need to see the reliever pitching better before activating him. If/when Diaz does return, he will likely be used in low-leverage spots, at least initially.

The Tigers optioned Diaz to Triple-A Toledo on Monday.

The move corresponds with the Tigers activating Keider Montero (personal) from the paternity list. In three outings after being recalled by Detroit on Aug. 31, Diaz has allowed four runs on four hits and three walks while striking out three across 4.1 innings.

The Dodgers recalled Gervase from Triple-A Oklahoma City on Monday, Fabian Ardaya of The Athletic reports.

Gervase has allowed two runs with an 8:5 K:BB over 7.2 innings during his time in the Dodgers' bullpen this season. He'll give manager Dave Roberts a fresh relief arm.

The Orioles optioned Hiraldo to Triple-A Norfolk on Monday.

Hiraldo was just recalled from Norfolk on Sunday and threw 49 pitches in Sunday's 8-1 loss to the Blue Jays, surrendering four runs on two hits and four walks. Codi Heuer has been recalled from Triple-A in a corresponding move.

The Orioles recalled Heuer from Triple-A Norfolk on Monday.

Heuer was acquired from Milwaukee for cash last month after he was dealt from Cleveland to the Brewers just three days prior. The right-hander posted a 4.66 ERA, 1.76 WHIP and 6:5 K:BB across 9.2 innings of relief with the Guardians this season.

The Blue Jays optioned Tiedemann to Triple-A Buffalo on Monday, Mitch Bannon of The Athletic reports.

Tiedemann made his MLB debut last month and has appeared in five games with the Blue Jays this season, allowing one run on five hits and six walks with eight strikeouts across six innings of relief.

The Blue Jays recalled Cellucci from Triple-A Buffalo on Monday, Mitch Bannon of The Athletic reports.

Toronto optioned Ricky Tiedemann in a corresponding move. Cellucci will be looking to make his MLB debut after he didn't appear in a game during his 48-hour stay with the Blue Jays last month. He owns a 3.16 ERA, 1.34 WHIP and 55:25 K:BB across 51.1 innings of relief at Triple-A this season.

Williams (shoulder) threw a live batting practice session Monday and will face hitters again Thursday, Anthony DiComo of MLB.com reports.

Williams does not anticipate needing a rehab assignment, so he could be activated from the 15-day injured list as soon as this weekend if things go well Thursday. He's been sidelined for a little over a month with a right shoulder strain. Kodai Senga has taken over the Mets' closer job and pitched well, so it's not a given that Williams will see save chances down the stretch if/when he's reinstated.

The Royals optioned McGee to Triple-A Omaha on Monday.

He'll be replaced on the roster and in the bullpen by Lucas Erceg. McGee had been scored up in two out of his previous three appearances for the Royals.

The Royals recalled Erceg from Triple-A Omaha on Monday.

Erceg was sent down one month ago and logged a 1.74 ERA and 13:3 K:BB over 10.1 frames covering nine appearances with Omaha. The 31-year-old has had a disastrous season with the Royals, posting a 6.23 ERA and 31:29 K:BB over 43.1 innings, but he will aim to finish on a high note.
