What It Means:

Guerra limped off the field after attempting a bunt in his first at-bat. He had allowed just one hit -- a two-run homer by Mark Reynolds -- through three innings. The injury could be severe enough to require a trip to the disabled list for Guerra. Tommy Milone relieved him on Monday and would be a good candidate to make a spot start if needed.

Our models projected for 11 wins with a 3.82 ERA and a 1.32 WHIP in 169 2/3 innings before the injury.
