I own Keppinger in all 4 leagues I play in. With SS being so weak this season, you cannot afford to bypass a guy with his early season production (.324 average, .373 OBP, steals, etc.) - especially if you have been starting a scrub like Izturis, Peralta, or Hardy in his place. Ugh.
He should be back late next week, or early in the first week of July.
