Mar 26 2025The Marlins designated Martinez for assignment Wednesday. ROTOWIRE RECOMMENDS: 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.
Mar 15 2025The Marlins claimed Martinez off waivers from Seattle on Saturday. ROTOWIRE RECOMMENDS: 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.
Mar 2 2025The Mariners claimed Martinez off waivers from the Marlins on Sunday, Daniel Kramer of MLB.com reports. ROTOWIRE RECOMMENDS: 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.
Feb 27 2025The Marlins designated Martinez for assignment Thursday. ROTOWIRE RECOMMENDS: Martinez was claimed off waivers from the Diamondbacks last Thursday, and after just a week with the Marlins he'll lose his spot on the 40-man roster in favor of Brett de Geus, who was picked up off waivers from Pittsburgh. 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.
Feb 20 2025The Marlins claimed Martinez off waivers from Arizona on Thursday. ROTOWIRE RECOMMENDS: The 30-year-old righty was pushed off the Diamondbacks' 40-man roster Monday to make room for Kendall Graveman (shoulder). 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.
Feb 17 2025The Diamondbacks designated Martinez for assignment Monday. ROTOWIRE RECOMMENDS: Martinez was cast off the 40-man roster with the Diamondbacks needing to clear a spot for newly signed right-hander Kendall Graveman (shoulder). The Diamondbacks had previously claimed Martinez off waivers earlier this offseason after he held a 3.59 ERA and 36:18 K:BB across 52.2 frames for Houston in 2024.
Nov 4 2024The Diamondbacks claimed Martinez off waivers from the Astros on Monday. ROTOWIRE RECOMMENDS: Martinez, 30, held a 3.59 ERA and 36:18 K:BB across 52.2 frames for Houston in 2024. He will provide the Diamondbacks with some additional right-handed relief depth.
Sep 24 2024The Astros optioned Martinez to Triple-A Sugar Land on Tuesday, Brian McTaggart of MLB.com reports. ROTOWIRE RECOMMENDS: Martinez had pitched two of the last three days, including Monday, and allowed four runs over 2.1 innings. He'll be replaced on the roster by fellow reliever Shawn Dubin.
Sep 21 2024The Astros recalled Martinez from Triple-A Sugar Land on Saturday ROTOWIRE RECOMMENDS: 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.
Aug 24 2024The Astros optioned Martinez to Triple-A Sugar Land on Saturday, Matt Kawahara of the Houston Chronicle reports. ROTOWIRE RECOMMENDS: 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.
Aug 21 2024The Astros recalled Martinez from Triple-A Sugar Land on Wednesday, Matt Kawahara of the Houston Chronicle reports. ROTOWIRE RECOMMENDS: Martinez was sent down earlier Wednesday but is back to fill the spot vacated by Kaleb Ort, who went on the paternity list. The Astros will likely option Martinez to Triple-A later this week when Ort returns.
Aug 17 2024The Astros recalled Martinez from Triple-A Sugar Land on Saturday, Matt Kawahara of the Houston Chronicle reports. ROTOWIRE RECOMMENDS: The move comes with Ryan Pressly heading to the 15-day injured list due to a lower back strain. Martinez was optioned to Sugar Land on July 31, and he has thrown 2.2 scoreless innings over his last three minor-league outings. He started the season in the majors, and across 41 outings with the Astros he's posted a 2.92 ERA and 1.22 WHIP across 49.1 innings.
Jul 31 2024The Astros optioned Martinez to Triple-A Sugar Land on Wednesday, Brian McTaggart of MLB.com reports. ROTOWIRE RECOMMENDS: Martinez is one of the casualties as the Astros officially add trade acquisitions Yusei Kikuchi and Caleb Ferguson to the 26-man active roster. He holds a 2.92 ERA but an ugly 34:18 K:BB over 49.1 innings with the Astros this season.
May 16 2024Martinez picked up the save in a win over the Athletics on Wednesday, allowing two walks over two innings while striking out one. ROTOWIRE RECOMMENDS: Martinez entered the contest with a three-run lead in the top of the eighth and struck out the first batter on seven pitches before issuing a walk to JJ Bleday. The right-hander would quickly work his way through it, however, thanks to a double play ball in the following at-bat, before returning for the ninth. Despite also issuing a walk in the final frame, Martinez was able to wrap up the game with another scoreless inning to notch his first save of the season. It was a nice bounceback effort for the reliever, who had allowed three runs in his previous appearance on May 12 against the Tigers. Closer Josh Hader covered two innings Tuesday while Ryan Pressly, Bryan Abreu and Rafael Montero pitched two straight days, which opened up the save chance for Martinez.
Apr 9 2024Martinez (1-0) allowed one hit and no walks while striking out two across 3.2 scoreless innings to earn the win Monday against the Rangers. ROTOWIRE RECOMMENDS: The Astros pitching staff was put in a tough position after Framber Valdez (elbow) was scratched. That was exacerbated after Blair Henley managed only one out while allowing five runs, but Martinez followed him into the game and managed to tally his 11 outs on just 32 pitches. Martinez is capable of working multiple innings in relief but has never started a big-league game, so he'll almost certainly return to a more traditional role out of the bullpen moving forward.
Sep 29 2023Houston recalled Martinez from Triple-A Sugar Land on Friday, Chandler Rome of The Athletic reports. ROTOWIRE RECOMMENDS: Martinez will join the Astros' bullpen ahead of Friday's series opener in Arizona as Ryne Stanek goes on paternity leave. Martinez, 29, has posted a 5.23 ERA and 1.49 WHIP through 43 major-league innings this season.
Aug 24 2023Houston optioned Martinez to Triple-A Sugar Land on Thursday, Matt Kawahara of the Houston Chronicle reports. ROTOWIRE RECOMMENDS: Brandon Bielak will fill the vacancy in the Astros' bullpen ahead of Thursday's series finale against the Red Sox. Martinez, 28, has struggled to a 5.23 ERA and 1.49 WHIP in 43 innings of relief this season at the major-league level.
Aug 21 2023Martinez was recalled from Triple-A Sugar Land on Monday, Matt Kawahara of the Houston Chronicle reports. ROTOWIRE RECOMMENDS: Martinez was optioned to the Triple-A level after being tagged for seven earned runs in his last appearance with the Astros, but he earned his way back to the big leagues by blanking the opponent in six the seven minor-league games he appeared in since the start of August.
Jul 29 2023Martinez was optioned to Triple-A Sugar Land on Saturday, Chandler Rome of The Athletic reports. ROTOWIRE RECOMMENDS: He gave up seven earned runs in one inning during his most recent performance Wednesday against the Rangers, and Kendall Graveman will take his place in the bullpen. The Astros could summon Martinez again next time they need a fresh bullpen arm.
Jun 25 2023Martinez struck out one batter in a perfect inning and earned a save against the Dodgers on Sunday. ROTOWIRE RECOMMENDS: Martinez recorded his first career save with a clean 11th inning Sunday. He followed Ryan Pressly's two innings of work and shouldn't be expected to see many save chances moving forward. Martinez lowered his ERA to 4.65 with a 33:14 K:BB through 31 innings this season.
Oct 28 2022Martinez was removed from the Astros' World Series roster Friday, Bob Nightengale of USA Today reports. ROTOWIRE RECOMMENDS: Martinez failed to pitch in any of the Astros' seven postseason games to this point and will now have to watch the World Series as a spectator. Will Smith will replace him on the roster and provide the Astros with a left-handed option out of the bullpen as the team takes on the Phillies in the Fall Classic.
Sep 16 2022Martinez was optioned to Triple-A Sugar Land on Friday, Chandler Rome of the Houston Chronicle reports. ROTOWIRE RECOMMENDS: Martinez was called up by the Astros in late August, and he allowed five hits and a walk while striking out seven in six scoreless innings over six relief appearances in the majors. In spite of his effective results, the right-hander will return to Sugar Land after Justin Verlander (calf) was reinstated from the 15-day injured list Friday.
Aug 25 2022Martinez was recalled from Triple-A Sugar Land on Thursday, Danielle Lerner of the Houston Chronicle reports. ROTOWIRE RECOMMENDS: The right-hander was sent down by the Astros in mid-August but will rejoin the big-league club Thursday with closer Ryan Pressly (neck) heading to the injured list.

Aug 13 2022Martinez was optioned to Triple-A Sugar Land on Saturday. ROTOWIRE RECOMMENDS: Martinez was productive over the first half of the season but has had inconsistent results over the last month.

May 17 2022The Astros recalled Martinez from Triple-A Sugar Land on Tuesday.

He's posted a 4.15 ERA in 8.2 innings over eight appearances in Sugar Land this season.
May 12 2022Martinez was recalled from Triple-A Sugar Land to serve as the 27th player for Thursday's game against the Twins, Chandler Rome of the Houston Chronicle reports. ROTOWIRE RECOMMENDS: Wednesday's contest was suspended and resumed ahead of Thursday's game, so the right-hander will provide bullpen depth for the impromptu twin bill. Martinez delivered a scoreless frame in his lone big-league appearance this season and has a 4.15 ERA, 1.22 WHIP and 9:4 K:BB over 8.2 innings at Sugar Land.
May 2 2022Martinez was optioned to Triple-A Sugar Land on Monday. ROTOWIRE RECOMMENDS: Martinez will lose his spot as rosters around the league shrink from 28 to 26. He'd been with the team since Tuesday but appeared just once, tossing one scoreless inning of relief Saturday against the Blue Jays.
Apr 26 2022Martinez was recalled from Triple-A Sugar Land on Tuesday, Brian McTaggart of MLB.com reports.
