Martinez, 30, logged a 3.59 ERA and 1.27 WHIP in 52.2 innings with the Astros last season, but it will be tougher for him to work back into the majors now that he no longer holds a spot on the 40-man roster.

Loses roster spot The Marlins designated Martinez for assignment Wednesday.

Impact After being claimed off waivers from the Mariners on March 15, Martinez's stay on Miami's 40-man roster lasted less than two weeks with the Marlins swapping him out for right-hander Tyler Phillips, whom the team acquired from the Phillies on Wednesday. Martinez spent most of the 2024 season in the majors with Houston, serving in a middle-relief role while logging a 3.59 ERA, 1.27 WHIP and 36:18 K:BB while collecting three wins, three holds and one save over 52.2 innings.

Claimed by Fish The Marlins claimed Martinez off waivers from Seattle on Saturday.

Impact Less than two weeks after moving from Miami to Seattle via waiver claim, Martinez will now head right back to Miami. The 30-year-old righty allowed four runs in just two-thirds of an inning during his lone appearance of the spring but his career 3.93 ERA should give him a good chance of sticking around in the Marlins' bullpen. Andrew Nardi (back) was placed on the 60-day injured list in a corresponding move.

Claimed by Seattle The Mariners claimed Martinez off waivers from the Marlins on Sunday, Daniel Kramer of MLB.com reports.

Impact Seattle will be Martinez's fourth team of the offseason after he finished the 2024 campaign with Houston. The 30-year-old made 44 regular-season appearances for the Astros last season and had a 3.59 ERA, 1.27 WHIP and 36:18 K:BB across 52.2 innings.

Impact Martinez was claimed off waivers from the Diamondbacks last Thursday, and after just a week with the team he'll lose his spot on the 40-man roster in favor of Brett de Geus, who was picked up off waivers from Pittsburgh on Thursday. Martinez finished last season with a 3.59 ERA and 1.27 WHIP over 52.2 regular-season innings with the Astros, so there could still be several teams willing to give him a spot on their 40-man instead.

Martinez spent all of last season with the Astros, turning in a 3.59 ERA and 1.27 WHIP alongside a 36:18 K:BB over 52.2 regular-season innings. Assuming he keeps a similar level of production during spring training, he'll have a good chance of winning a spot in Miami's Opening Day bullpen. Eury Perez (elbow) was placed on the 60-day injured list in a corresponding move.

FEBRUARY 20, 2025 • ROTOWIRE

Booted from 40-man roster The Diamondbacks designated Martinez for assignment Monday, Alex Weiner of ArizonaSports.com reports.

Back in big leagues The Astros recalled Martinez from Triple-A Sugar Land on Saturday

Impact With Tayler Scott (back) headed for the injured list, the Astros will call upon Martinez to fill the open spot in the bullpen. The 30-year-old righty has been solid in the majors this season, posting a 3.04 ERA and 1.21 WHIP through 50.1 innings. He'll most likely work in middle relief down the stretch.

SEPTEMBER 21, 2024 • ROTOWIRE

Impact Martinez will be squeezed out of the Astros' bullpen in order to make room for Hector Neris, who signed with the team Thursday. With a 3.04 ERA and 1.21 WHIP through 50.1 innings, the 29-year-old Martinez remains a candidate to return to Houston's bullpen down the stretch.
