Just a year removed from pitching the 21st perfect game in major league history, Humber had a terrible start to 2013. He was 0-8 with a 9.59 ERA.
He started the season in the rotation, but was moved to the bullpen on Wednesday. He threw 1 1/3 scoreless innings in relief on Thursday before taking the loss in his second relief appearance on Saturday night.
