Montero (1-2) allowed three runs (two earned) on two hits while retiring one batter to blow a save and take the loss in Saturday's extra-innings contest against the Marlins.

EDGE Analysis

With Will Vest having already pitched the ninth and 10th innings, the Tigers had to turn to Montero in the 11th to protect a 4-3 lead. The veteran righty couldn't get the job done in an ineffective performance. Montero has a rough 4.88 ERA overall this season, though he's been better since joining Detroit before the trade deadline, posting a 3.71 ERA across 17 innings so far. He should remain in a middle-relief role with limited fantasy appeal.

Montero tossed 2.2 scoreless innings of relief in Wednesday's 7-0 loss to the Athletics. He walked one batter and struck out four.

EDGE Analysis

After starter Casey Mize was tagged for five runs in just 3.1 innings, Montero came on and gave the Tigers some valuable long relief. It was the veteran righty's longest outing of the season, and he's now covered two or more innings four times this year. Montero has been fairly effective in Detroit since coming over before the trade deadline, posting a 3.48 ERA and 1.06 WHIP across 10.1 innings with his new team.

Montero (1-1) worked 1.1 scoreless innings of relief to earn the win in Thursday's 4-3, 11-inning victory over the Twins. He struck out two.

EDGE Analysis

Montero was needed to record the final four outs of the game, as Kyle Finnegan pitched earlier in the contest and Will Vest wasn't used after recording a save Wednesday. While Montero has pitched better his last two appearances after a rough debut with the Tigers, the veteran righty is still hard to trust with a 5.52 ERA and 1.39 WHIP on the season. He'll continue to work in a middle-relief role, with Finnegan and Vest seeing the bulk of Detroit's late-inning work.

Montero tossed 1.2 scoreless innings of relief in Saturday's 7-4 loss to the Angels. He allowed a hit and struck out one.

EDGE Analysis

After allowing two earned runs in an inning during his team debut Tuesday, Montero was better in his second outing since coming over at the trade deadline. The righty is still carrying a 5.49 ERA overall, making him hard to trust in any fantasy format given his middle relief role. Montero should continue to see medium-leverage work for the Tigers.

Montero allowed two runs on two hits and a walk across an inning of relief in Tuesday's 6-3 loss to the Twins.

EDGE Analysis

Montero, who was traded to Detroit from Atlanta before last Thursday's deadline, was making his first appearance in exactly a week. Perhaps as a result of some rust, the veteran righty wasn't particularly sharp in his team debut, and his season ERA climbed to 5.72. Montero can miss some bats, as he has 39 strikeouts in 39.1 innings this year, though he's too volatile at this point to see high-leverage work with the Tigers, which minimizes his fantasy appeal.

Atlanta traded Montero to Detroit on Wednesday in exchange for infielder Jim Jarvis.

EDGE Analysis

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. His poor performance will likely restrict him to working as a middle reliever while with the Tigers.

Montero gave up a hit in a scoreless seventh inning Friday to record his sixth hold of the season in a win over the Cardinals.

EDGE Analysis

The veteran right-hander has provided some stability in middle relief for Atlanta since coming over from Houston in early April. Over 30 appearances for the NL East squad, Montero has posted a 3.72 ERA, 1.21 WHIP and 30:15 K:BB in 29 innings, although he has yet to notch a win or a save in 2025.

The Astros traded Montero and cash to Atlanta on Tuesday in exchange for a player to be named later.

EDGE Analysis

Montero has made three appearances out of the bullpen so far this season, giving up two earned runs while striking out five batters across four innings. Now in Atlanta, the 34-year-old reliever will likely remain in the major-league bullpen, but he isn't expected to see many high-leverage opportunities.

The Astros selected Montero's contract from Triple-A Sugar Land on Thursday, Brian McTaggart of MLB.com reports.

EDGE Analysis

Montero was removed from the Astros' 40-man roster last season but has made his way back on. He will operate in middle relief.

Montero reported to Astros camp Monday after previously dealing with visa issues, Chandler Rome of The Athletic reports.

EDGE Analysis

Montero wound up being only a few days late in reporting, so his preparation shouldn't be too affected. He's owed $11.5 million in the final year of his contract but is in camp as a non-roster invitee.
