The Cardinals will be closing their 10-game road trip and the Giants preparing to head out on one of their own as the two postseason hopefuls meet for the final time this season in a Sunday matinee game at AT&T Park. Chris Heston, who will be pitching on 12 days' rest, will be countered by Cards lefty Jaime Garcia, whose 1.77 ERA is the second lowest among all Major League starters with at least 13 starts.
