An MRI exam Tuesday revealed inflamation in the finger, Bochy said. Scutaro also injured his left pinkie when it was hit by a pitch from Pittsburgh's Tony Watson on June 11.
In another injury-related matter, Bochy said right-hander Sandy Rosario, who injured his right hip trying to pitch in Tuesday's ninth inning, will be sidelined for at least a couple of days.
"Hopefully we'll get him on the mound before the season's over," Bochy said.
