Manager Ron Washington said Sunday that the club will "back off" Rengifo due to his hamstring injury, and he may not be ready for Opening Day, Rhett Bollinger of MLB.com reports.
The 27-year-old downplayed the hamstring issue as a cramp after he was scratched from the lineup last Monday, but the injury appears to be a bit more problematic after he was scratched again Saturday. Rengifo has seen action in just one Cactus League game so far, leaving him just two and a half weeks to get right before Opening Day against the White Sox on March 27.
