What has happened to this guy, the Detroit Tigers today placed him on the DL with anxiety disorder. He was being compared to Vida blue just a few years ago and the last few years has been horrible he came back for the last few games last year and finished with a 0-2 record and 9.38 ERA, walking 35 batters, allowing 18 hits and getting 18 strikeouts in 24 innings. I feel bad for him because he had so much potential just a few years ago i hope he can get better and back to the form he once was.
