(AP) — Hunter Pence broke his left forearm and will be sidelined six to eight weeks after being hit by a pitch in the sixth inning of the San Francisco Giants' 8-6 win over a Chicago Cubs split-squad on Thursday. Jeremy Affeldt allowed a run in one inning as the Giants won their first in three exhibition games between the teams. Jacob Turner threw two scoreless innings in his spring debut with the Cubs. Turner, who came to the Cubs last August in a trade with the Miami Marlins, is in the mix for a spot in the starting rotation. Matt Cain threw batting practice for the second time and could start an exhibition game in his next scheduled outing.
