The Pirates placed Nicolas on the bereavement list Friday.

Nicolas will be permitted to miss 3-7 games while he tends to more important matters. Evan Sisk was recalled from Triple-A Indianapolis in a corresponding move and will take Nicolas' place in Pittsburgh's bullpen.

The Brewers activated Zastryzny (ribs) from the 15-day injured list Friday.

Zastryzny has been out since late June with a stress reaction in his ribs but is ready to go after overcoming a previous setback. He'll give manager Pat Murphy another left-handed option in the bulllpen.

The Brewers optioned McGee to Triple-A Nashville on Friday.

McGee had thrown 3.2 innings covering two appearances over the last two days, so he wasn't going to be available to pitch for a day or two. Rob Zastryzny (ribs) is coming off the injured list to take McGee's roster spot.

The Mets optioned Herget to Triple-A Syracuse on Friday.

Herget will cede his spot on the active roster to Jonah Tong. Herget was called up Wednesday and threw 2.2 scoreless innings against the Marlins on Thursday. The 34-year-old has a 2.00 ERA in 27 innings with Syracuse in 2025.

Helsley thinks his struggles since joining the Mets are a result of tipping pitches, Will Sammon of The Athletic reports. "I think I know how to fix it," the right-hander said Thursday. "So it's just being able to enforce that and that being my mental norm versus what I was doing to get my body to accept that and reinforce that."

The former Cardinals closer has a brutal 10.38 ERA, 2.31 WHIP and 11:7 K:BB in 8.2 innings with the Mets, and he's been tagged with multiple earned runs in four of his last six appearances. "It definitely stinks," Helsley said. "I've never gone through anything like this in my career." He's still looking for his first hold for New York after being acquired at the trade deadline to be the top set-up man for Edwin Diaz, instead taking three losses and getting charged with four blown saves.

Atlanta optioned Suero to Triple-A Gwinnett on Friday.

Atlanta is supplementing its bullpen after Cal Quantrill's abbreviated start Thursday in Philadelphia. Suero gave up a couple runs while recording just one out in that loss and now finds himself back in the minors a day later.

Atlanta optioned Cox to Triple-A Gwinnett on Friday.

Cox was hammered for seven runs in a three-inning relief appearance Thursday in Philadelphia, throwing 68 pitches. He wasn't going to be available to pitch for a few days, so Atlanta is replacing him with a fresh bullpen arm.

Atlanta recalled Wiles from Triple-A Gwinnett on Friday.

Wiles was knocked around in his major-league debut earlier this season with Atlanta, allowing three runs over one inning. He's been used mostly as a starter at Gwinnett, so Wiles will offer length in the bullpen after starter Cal Quantrill lasted only 3.1 innings in Thursday's loss to the Phillies.

Atlanta selected Brebbia's contract from Triple-A Gwinnett on Friday.

Brebbia posted a 1.89 ERA and 21:3 K:BB over 19 innings with Gwinnett after inking a minor-league contract with Atlanta in June. The veteran reliever holds an unsightly 7.71 ERA at the big-league level this season and will work in middle relief.

The Mets outrighted Adcock to Triple-A Syracuse on Thursday.

The 28-year-old is now off the Mets' 40-man roster, clearing a spot for Jonah Tong, who was called up from Syracuse to make his major-league debut Friday versus the Marlins. Adcock has made three appearances in the big leagues this season, allowing one run while striking out five over three frames.
