SAN FRANCISCO -- The Giants have shuffled plenty of players in and out of the lineup this season, particularly in the outfield. But when it comes to their 25-year-old center fielder, they're willing to let Steven Duggar take his lumps.Duggar's defense is such a plus that he brings something to the table on a nightly basis even when he's slumping. And as the staff has watched him try and adjust to big league pitching, there hasn't been much concern about the mental side of the game.
