Cardinals optioned RHP Mitchell Boggs to Triple-A Memphis. After losing the closer job, Boggs wasn't able to figure things out in setup and mop-up roles, so he'll try to work out the kinks at Triple-A. The Cards will continue to use Trevor Rosenthal as the primary setup man to Edward Mujica. The club has not announced a corresponding move, but John Gast is receiving consideration for a promotion.
