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.

Montero has yet to report to camp due to visa issues but is expected to arrive in a few days, Chandler Rome of The Athletic reports.

EDGE Analysis

Montero was removed from the Astros' 40-man roster last August but remained in the organization and will be in camp as a non-roster invitee when he does report. The 34-year-old held a 4.70 ERA, 1.41 WHIP and 23:19 K:BB across 38.1 innings in 2024 and is owed $11.5 million in the final year of his contract.

Montero cleared waivers and was outrighted by the Astros to Triple-A Sugar Land on Saturday.

EDGE Analysis

Montero was DFA'd by Houston on Wednesday, but he didn't garner interest from another team and has elected to stay within the organization rather than enter free agency. Montero has appeared in 41 games for the Astros this season, registering 10 holds with a 4.70 ERA, 1.41 WHIP and 23:19 K:BB across 38.1 innings.

The Astros designated Montero for assignment Wednesday.

EDGE Analysis

Montero is in the second year of a three-year, $34.5 million contract, and the Astros appear willing to absorb what remains on that deal. The veteran reliever made 41 appearances for Houston this season, posting a 4.70 ERA and 23:19 K:BB over 38.1 innings. Montero will likely pass through waivers unclaimed and will have the ability to elect free agency.

Montero allowed one walk and no hits while striking out one across a scoreless inning to earn a hold Saturday against the Nationals.

EDGE Analysis

The Astros were projected to have a strong bullpen with Josh Hader, Ryan Pressly and Bryan Abreu all leading the way in high-leverage situations. However, each has struggled to begin the new campaign, while Montero has now turned in nine scoreless performances in 11 appearances. He's pitched primarily in the sixth and seventh innings this season, though he could earn higher-leverage work given his solid start.

Montero (0-1) allowed four earned runs on three hits and a walk to take the loss Saturday against the Mariners.

EDGE Analysis

Montero was tasked with protecting a three-run lead in the eighth inning, and he retired the first two batters he faced. However, he allowed the next four batters he faced to reach base -- two of which were on infield singles --to suffer the ugly line and his first loss of the campaign. Montero has otherwise been solid, as he had turned in scoreless appearances in 10 of his 14 previous opportunities.
