Sonny Gray Injury: Has been battling flu

Gray has been battling the flu recently, which has sapped him of his strength, Derrick Goold of the St. Louis Post-Dispatch reports.

It could help explain why Gray's velocity has been down this spring, though the righty suspects that starting his offseason throwing program later than usual also played a part. Gray said Monday that he's feeling better, and it does not seem as though his availability for Opening Day on Thursday is in question.
