March 28, 2025
Martinez cleared waivers Friday and was sent outright to Triple-A Jacksonville.
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.

Latest Fantasy Rumors
Could start Saturday
PHouston Astros  AAA
May 17, 2022
Astros manager Dusty Baker confirmed Martinez is an option to start Saturday against the Rangers, according to Molly Burkhardt of MLB.com.
ANALYSIS
Even though Cristian Javier is the likeliest candidate to take over for Jake Odorizzi in the rotation if the latter is forced to miss time, don't rule out the chance of Martinez starting during the upcoming weekend series against Texas. The right-hander is currently on the taxi squad and owns a 4.15 ERA across eight relief appearances at the Triple-A level in 2022. He's also made two MLB appearances, giving up one hit and posting a 1:4 BB:K over 2.2 innings.
