A squirrel ran onto the field during Friday night’s game between the Yankees and the Red Sox and caused a brief delay. The fast-moving mammal emerged from an area behind the plate in the fourth inning and stopped behind Boston rookie Jhostynxon Garcia’s left foot as the outfielder took a timeout and adjusted his batting gloves.
