"Just to have a guy who knows what he's doing is a big confidence boost," Grandal said on Thursday. "He knows what you need to work on: setting up, pitch selection, recognizing how to block a ball, how to set-up for a pitch in different type of counts."
Grandal was in the starting lineup Thursday for the first of four games against the Reds at Petco Park.
