The Pittsburgh Pirates will have the advantage of recent form and revenge motivation when they open a three-game series against the San Francisco Giants on Monday night at AT&T Park. Pirates right-hander Gerrit Cole (7-7, 4.18 ERA), unbeaten in July, will duel Giants righty Matt Cain (3-8, 5.49), who hasn't won since May, in a rematch of teams that met in Pittsburgh three weeks ago. The Giants swept that three-game series, bombing Cole for seven runs on 10 hits in 5 1/3 innings in a 13-5 drubbing on June 30.
