RHP Cody Anderson is being sent down to AAA Columbus, and taking his spot on the roster will be LHP Kyle Crockett. Anderson has not got off to a good start this year; in the 4 games that he's started, he's carrying an ugly ERA of 7.65 and has given up 17 runs in 20 innings (good for an ERA+ of 53).
Kyle Crockett, drafted in the 4th round of the 2013 draft by the Tribe, found his way onto the big league club in 2014 and pitched very well; in 30 innings, he had only given up 8 earned runs while striking out 28 (good for an ERA+ of 219).
