Detroit acquired Montero from Atlanta on Wednesday in exchange for infielder Jim Jarvis.

Montero will join his third team of the season after logging a 5.40 ERA and 1.38 WHIP across 38.1 innings between Atlanta and Houston. He'll likely fill a middle-relief role for Detroit.

The Mariners optioned Kowar to Triple-A Tacoma on Wednesday.

The Mariners had to make room in their bullpen after acquiring Caleb Ferguson from Pittsburgh on Wednesday, and Kowar will officially end up as the roster casualty. The 28-year-old righty pitched three scoreless innings after being recalled from Triple-A on Thursday, lowering his big-league ERA to 1.54 through 11.2 frames this season.

Vasil (5-3) earned the win Wednesday over the Phillies, allowing three hits while striking out three over four scoreless innings.

Vasil worked as a bulk reliever and managed to keep a high-powered Phillies offense at bay before the White Sox rallied for seven runs in the seventh inning, en route to a 9-3 victory. The 25-year-old Vasil has been excellent of late, posting a 0.61 ERA over his last seven appearances (14.2 innings). Overall, his ERA sits at an impressive 2.35 with a 1.22 WHIP and 51:36 K:BB across 69 innings in his rookie campaign.

Allard didn't factor into the decision Wednesday against the Rockies, allowing one hit and no walks in 3.1 scoreless innings. He struck out five.

It was an impressive showing in limited action by Allard, who set a season-high in strikeouts Wednesday. The southpaw held the Rockies to a lone single, and he managed to register seven whiffs despite firing just 42 pitches. Through his first 44.2 innings, Allard has a 2.62 ERA, 1.28 WHIP and 28:10 K:BB. If the Guardians need to throw another bullpen game, Allard's next turn in the rotation lines up for next week in Queens against the Mets.

The Rangers placed Webb on the 15-day injured list Wednesday, retroactive to Tuesday, due to back spasms.

Webb may have started feeling symptoms during his last outing Monday against the Angels, when he allowed one run on two hits while striking out four across 1.2 innings. He'll undergo further testing to determine the severity of the injury and an estimated schedule for a return, but his absence will require the Rangers to lean more on Cole Winn and Caleb Boushley for relief work. The Rangers recalled Luis Curvelo from Triple-A Round Rock in a corresponding move.

The Rangers recalled Curvelo from Triple-A Round Rock on Wednesday, Daniel Alvarez-Montes of ElExtraBase.com reports.

Curvelo spent time on the Rangers' taxi squad in early June but never received a spot on the 26-man roster. He'll officially join Texas' bullpen this time, however, after logging a 3.26 ERA and 1.28 WHIP with 40 strikeouts through 38.2 innings at Round Rock. The 24-year-old righty will be making his MLB debut whenever he gets into a game.

Blue Jays manager John Schneider said Wednesday that Garcia (ankle/elbow) could be a week or so away from resuming a throwing program, Ben Nicholson-Smith of Sportsnet.ca reports.

Though Garcia was placed on the injured list July 5 due to a left ankle sprain, the Blue Jays recently revealed that he had also been experiencing ulnar nerve symptoms in his right elbow. He received a cortisone shot last week to address the elbow issue, and the Blue Jays are still waiting for the injection to alleviate some of the discomfort before clearing him to throw. The reliever will probably require a minor-league rehab assignment prior to being activated, so he's unlikely to be an option for the Toronto bullpen until the second half of August.

The Pirates traded Ferguson to the Mariners on Wednesday in exchange for Jeter Martinez, Jeff Passan of ESPN.com reports.

Ferguson signed a one-year contract with the Pirates in January after spending the 2024 season with the Astros and Yankees. The 29-year-old southpaw has and 3.74 ERA, 1.08 WHIP and 34:14 K:BB across 43.1 innings this season. Ferguson boasts the lowest hard-hit rate the majors (25.2 percent ) and has given up just one home run this season, and he'll give the Mariners a reliable setup man out of the bullpen.

Cano (1-6) was charged with the loss in Wednesday's 9-8 defeat to the Blue Jays, allowing five runs on four hits and no walks with no strikeouts in two-thirds of an inning.

The five runs allowed were a season high for Cano, who served up a home run for the first time since his June 18 outing in Tampa Bay. Although closer Felix Bautista (shoulder) is on the shelf and Seranthony Dominguez has been traded away, Wednesday's showing doesn't bode well for the possibility of Cano receiving future save opportunities. Since the start of May, Cano has a dreadful 7.22 ERA, 1.64 WHIP and 30:13 K:BB covering 28.2 innings.

Baker (calf) struck out one batter over a perfect inning of relief in Tuesday's 7-5 loss to the Yankees.

Baker suffered a right calf strain during his most recent appearance Saturday against the Reds, but he was able to avoid a trip to the injured list and was sharp in his return to the mound three days later. Since being acquired from the Orioles on July 10, Baker has collected two holds and has permitted six earned runs on four hits and four walks over 5.2 innings.
