Corey Kluber was magnificent in his final spring start on Thursday, shutting out the D'Backs on one hit over four innings. Kluber ends spring training on a high note. He entered Thursday's start with a 6.64 ERA, but also a 16/2 K/BB ratio. With five strikeouts and no walks against the D'Backs, that ratio jumps up to 21/2. While he won't average better than ten strikeouts for every one walk during the regular season, his spring K/BB ratio speaks more to his talent than his spring ERA.
