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.

Latest Fantasy Rumors
Could start Saturday
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.
