ST. LOUIS (AP) Hunter Pence of the San Francisco Giants was undergoing an MRI exam for a left oblique injury and was not in the lineup against the St. Louis Cardinals.
Manager Bruce Bochy anticipated having results after Tuesday night's game.
Pence was hurt swinging on a fly out against St. Louis closer Trevor Rosenthal in the ninth inning of a 2-1 loss Monday night.
Bochy had planned to give Pence a day off Tuesday. Justin Maxwell played right field and was batting eighth.
