Ryan Vogelsong gave up a grand slam to Kyle Schwarber, the Cubs first pick of last June's draft, but the San Francisco Giants rallied to beat a Chicago split-squad 8-6 on Thursday. Giants' outfielder Hunter Pence left the game after getting hit by a pitch in the sixth inning. Jeremy Affeldt allowed a run in one inning as the Giants won their first in three exhibition games between the teams.
