Also, top 10 guy entering the season Cody Buckel has suffered a complete implosion. He had a great year last year and had an outside shot to make the big league club entering this year. He threw 9.1 IP in Double-A with a 20.25 ERA (29 runs) with 28 BB. No typos there. They assigned him to extended spring where he seems to be rotting away. John Sickels says "pitchers will break your heart" in reference to him and he's right. Crazy collapse.
