The Mets designated Garcia for assignment Sunday.

The right-hander was claimed off waivers by the Mets on July 21, and he pitched well in six appearances with three runs allowed and a 13:3 K:BB over eight innings. Garcia surrendered two earned runs Saturday versus the Giants, however, and has now lost his place on the 26-man active roster and 40-man roster. Austin Warren was called up from Triple-A Syracuse in a corresponding move.

The Mets recalled Warren from Triple-A Syracuse on Sunday.

Warren has had a few brief stints in the majors this season and has given up one earned run with a 4:3 K:BB over 5.1 innings with the Mets. He's been less effective in 24 outings with Syracuse this season with a 5.20 ERA and 1.41 WHIP.

The Yankees placed Loaisiga on the 15-day injured list Sunday due to right mid-back tightness.

The injury presumably surfaced during Loaisiga's appearance against Miami on Friday, when he allowed one hit and plunked a batter while recording just one out. The right-hander will be eligible to be reinstated in mid-August, though a timeline for his return likely won't be established until he meets with the Yankees' team physician back in New York, according to Bryan Hoch of MLB.com.

The Astros optioned Contreras to Triple-A Sugar Land on Sunday.

Contreras was sent out to make room in the bullpen for John Rooney, who was acquired from Miami. During his week-long stay with the Astros, Contreras appeared in two contests and struck out three batters over three scoreless innings.

Leasure didn't strike out a batter in a perfect ninth inning to earn the save in Saturday's 1-0 win against the Angels.

Aaron Civale and Brandon Eisert combined to allow just one hit through eight innings, and Leasure finished things off by retiring the side in the ninth on just nine pitches. The White Sox haven't had a consistent closer this season, with Leasure and Grant Taylor tied for the team lead with three apiece. Taylor offers more upside and a classic closer arsenal, but the White Sox seem uncertain whether they want to develop the top prospect exclusively as a high-leverage reliever.

Richardson was brought up from Triple-A Louisville to serve as the 27th man for Sunday's game against Atlanta.

After the Speedway Classic was suspended Saturday in the first inning following multiple rain delays, Atlanta and Cincinnati will resume the game Sunday. Because starter Chase Burns won't pitch after tossing a perfect inning a day earlier, the Reds will lean on a slew of relievers to get them through the contest. Richardson will be a candidate to head back to Louisville immediately after the contest.

Vest worked the eighth inning of Saturday's 7-5 win over the Phillies and allowed two runs on three hits while retiring two batters via strikeout.

After seven strong innings from starter Tarik Skubal, Vest worked the eighth inning with the Tigers up 7-3. He came on to face the top of Philadelphia's order in Trea Turner, Kyle Schwarber and Bryce Harper, and Harper tagged him for a two-run home run. After Vest departed, the newly acquired Kyle Finnegan came on to record the final four outs and earn his first save with his new team. Detroit manager A.J. Hinch may mix and match with his revamped bullpen, and if Vest is used more frequently in high-leverage spots before the ninth inning, his fantasy value could take a hit due to a decrease in save opportunities.

Romero allowed one run on two hits and one walk over 1.1 innings to earn the save Saturday against the Padres. He did not record a strikeout.

The left-hander recorded the final out of the eighth inning and returned for the ninth to notch St. Louis' first save since trading former closer Ryan Helsley, though Romero didn't have his cleanest performance. Still, the 29-year-old has been a reliable high-leverage option this season, with Saturday's earned run being the first he's given up since June 26. Riley O'Brien and Gordon Graceffo could also be in the mix for saves, but it's notable that Romero received the first opportunity.

Thielbar (2-3) allowed two runs on two hits and a walk while retiring only two batters to take the loss in Saturday's 4-3 defeat to the Orioles.

After seven scoreless innings from starter Matthew Boyd, relievers Ryan Brasier and Thielbar coughed up the lead in the eighth. The key play was a three-run home run by Gunnar Henderson off Thielbar, which saddled the veteran lefty with the loss. Thielbar still has a strong 2.36 ERA and 0.86 WHIP across 42 innings this season, and he should remain a key piece of Chicago's bullpen despite the hiccup.

Faucher earned a save against the Yankees on Saturday, striking out one batter in a perfect inning of work.

The Marlins led 2-0 when Faucher entered in the ninth frame, and he preserved the shutout by retiring the side in order on 12 pitches. Miami's bullpen hierarchy has been difficult to nail down for much of the season, but it appears Faucher could be settling into the closer role -- he's picked up three of the team's past four saves, with the only save that went to another pitcher during that span being a four-inning conversion by Tyler Phillips. Faucher has earned the confidence of manager Clayton McCullough by giving up just two runs over 10.2 frames while posting a 13:4 K:BB across 10 appearances since the start of July.
