SAN FRANCISCO (AP) Oakland Athletics outfielder Billy Burns left Friday night's game against the San Francisco Giants after the third inning with a testicular contusion, the result of fouling off a ball during his at-bat in the top of the inning.

Burns took several minutes to gather himself following the incident and finished the at-bat. He recorded an RBI groundout.

Mark Canha went into the game to play left field and Sam Fuld moved to center field.
