MINNEAPOLIS -- Minnesota Twins right-hander Ervin Santana may miss the rest of the season while receiving a series of platelet rich plasma injections in the middle finger of his pitching hand.
Santana is 0-1 with a 8.03 ERA in five major league starts this season.
"He had one done," Minnesota manager Paul Molitor said Saturday. "I think over a three-week period he'll have that done three times."
Santana had surgery Feb. 6 to remove a calcium deposit on the finger. He made his first minor league injury rehabilitation appearance May 23 and didn't make his season debut for the Twins until July 25.
