Scott Rolen (shoulder) recently received a cortisone shot. Rolen was placed on the disabled list earlier this month with a strained left shoulder and has yet to resume swinging a bat. Reds manager Dusty Baker said on Saturday that he's not sure when the 37-year-old third baseman will be ready to return. With his future very much in doubt, Todd Frazier makes for a smart pickup in deeper mixed formats.
