Marco Scutaro received an epidermal injection in his ailing back on Thursday. Scutaro said it was the second shot he's been administered after the first one didn't work. Giants manager Bruce Bochy retains hope that Scutaro can play by the weekend. Bochy said it's 50-50 odds right now that Scutaro will start the year on the DL and he'd like to make a decision soon to protect the player's retroactive DL days.
