The Reds still have a shot at a winning record but must turn around their current fortunes, losers of three straight games heading into Monday night’s series opener in St. Louis. The Reds were swept by the Athletics in Sacramento this weekend, including a 7-4 loss on Sunday afternoon. Noelvi Marte and Will Benson each homered for the Reds in the loss.
