ANALYSIS
A former top pitching prospect while coming up through the Houston farm system, Martes made his big-league debut in his age-21 season in 2017. Since then, his career has been derailed by the Tommy John procedure he required in August 2018 along with two lengthy suspensions for testing positive for performance-enhancing drugs. Now 25 years old, Martes struggled mightily in a relief role at Triple-A Sugar Land this season, giving up 17 earned runs on 10 hits and 20 walks over 11.2 innings. He'll look to reboot his career in another organization with Houston electing to pull the plug on him.
