With Jon Gray likely out of the race for the fifth spot in the Rockies' rotation, the club will evaluate Christian Bergman and Eddie Butler over the weekend before making a final decision, according to the Denver Post.
Bergman is slated to pitch in a Cactus League game Friday against the Mariners. He has 5.52 ERA over 14 2/3 innings of work this spring. Butler will face Seattle on Saturday. He owns a 3.07 ERA over 14 2/3 innings this spring.
