Martinez elected free agency Saturday after clearing waivers.
EDGE Analysis
Rather than remaining in the Miami organization as relief depth at Triple-A Jacksonville after being pushed off the 40-man roster, Martinez will head to the open market in search of a new opportunity. In six appearances for the big club this season, Martinez has posted a 5.40 ERA, 1.05 WHIP and 4:3 K:BB in 6.2 innings.

The Marlins designated Martinez for assignment Thursday.
EDGE Analysis
Martinez has made six appearances since joining the active roster Aug. 27, during which he's coughed up four earned runs across 6.2 innings. He'll now lose his place on the MLB and 40-man rosters to make room for Ryan Weathers' (lat) return from the 60-day IL.

The Marlins selected Martinez's contract from Triple-A Jacksonville on Wednesday.
EDGE Analysis
Martinez has spent the entire 2025 season at Jacksonville, posting a 3.71 ERA and 54:18 K:BB over 43.2 innings. He will likely operate in a middle-relief role.

Martinez cleared waivers Friday and was sent outright to Triple-A Jacksonville.
EDGE Analysis
Martinez was DFA'd by Miami on Wednesday to make room for Tyler Phillips but will officially remain with the organization after passing through waivers unclaimed. 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.

The Marlins designated Martinez for assignment Wednesday.
EDGE Analysis
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.

The Marlins claimed Martinez off waivers from Seattle on Saturday.
EDGE Analysis
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.

The Mariners claimed Martinez off waivers from the Marlins on Sunday, Daniel Kramer of MLB.com reports.
EDGE Analysis
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.

The Marlins designated Martinez for assignment Thursday.
EDGE Analysis
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.

The Marlins claimed Martinez off waivers from Arizona on Thursday.
EDGE Analysis
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.

The Diamondbacks designated Martinez for assignment Monday.
EDGE Analysis
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.
