Sanchez goes on 7-day DL
Sanchez left Friday night's game against the Dodgers early after being struck in the face mask by a foul ball.
He is batting .196 with three homers and 28 RBIs. The Giants recalled catcher Andrew Susac from Triple-A Fresno to take his place on the 25-man roster.
Giants manager Bruce Bochy said Sanchez was feeling better but it was too early to tell how much time he would miss.
