RHP Neftali Feliz.
It should first be noted that Neftali Feliz hasn't pitched in a big-league game since May 2012 and that was as a starting pitcher before he was shut down and let underwent Tommy John surgery to reconstruct his pitching elbow.
Of course, that used to be a death sentence to a pitcher, but sometimes nowadays guys come back and are even stronger than they were before, but it can take a while.
That's why we shouldn't expect a whole lot from Feliz when and if he does return to the Rangers, but that time is coming soon and he'll provide depth in the bullpen, if nothing else.
Feliz worked a perfect inning of relief on Thursday at Triple-A Round Rock, throwing only nine pitches and getting one strikeout against Houston's Triple-A team from Oklahoma City. That's about as dominant as it gets in what was his fourth appearance on his current rehab assignment.
Feliz still has some obstacles to work past, such as pitching on back-to-back days and pitching more than one inning, but the plan all along has been to bring the 25-year-old back as a reliever, not as a starter.
In 2010, Feliz racked up 40 saves in the regular season and earned AL Rookie of the Year honors as the Rangers went to their first World Series in franchise history.
