Zack Greinke left Tuesday's start against the Philadelphia Phillies after two innings with tightness in his left oblique.

Greinke hit a bases-loaded sacrifice fly to score a run for the Arizona Diamondbacks in the second inning and left after a few warm-up pitches before the start of the third.

Chip Hale said there was no way he was going to risk his pitcher worsening the injury.

"It's something maybe he can maybe miss a start, possibly not miss a start; possibly at worst, maybe 15 days on the DL," Hale said. "You never know. But if you go out and really yank it bad, you're talking about a month or two, so we'll hope for a best-case scenario."
