Arizona Diamondbacks ace Zack Greinke is in danger of missing the team's Opening Day game against the Colorado Rockies on March 29 due to a groin injury.
According to Nick Piecoro of AZCentral.com, Diamondbacks manager Torey Lovullo said he doesn't want to rush Greinke back into action: "He's going to have to get ahead of it and be well ahead of it before he puts himself in [position to start Opening Day]. My mindset is to not have him play catch-up for one day during the season. We want to make sure he's strong from Day 1 until the end of the season.
