Diamondbacks' Zack Greinke leaves start with groin tightness

Arizona Diamondbacks pitcher Zack Greinke (groin) left after one inning in his start against the Cincinnati Reds on Wednesday.

What It Means:

It's unclear how serious of an injury it is, but Arizona will likely provide an update after the game. Greinke was already dealing with decreased velocity this spring, so it can't make fantasy owners and Diamondbacks fans rest any easier to see this news.

numberFire projects Greinke for a 3.48 ERA, 1.14 WHIP, and 181 strikeouts across 199 2/3 innings this season.
