Cubs sign veteran lefty Trever Miller

The Cubs signed veteran lefty, Trever Miller, to a minor league deal today. Miller, 38, put up a respectable 3.81 era but had problems throwing strikes (5.1 BB/9) and gave up over a hit per (10.5 H/9) in 21 innings with three teams last year. His last good season was 2009 (0.96 WHIP & 4.15 K/BB) so unless the Cubs catch lighting in a bottle, Miller will provide LH depth at Iowa. If none of the Cubs young lefty arms (Gaub, Maine, Beliveau) pan out or a few guys get hurt, Miller could see some action in the bigs. It's not an impact move, but no risk either and it never hurts to have a few extra lefty arms. Maybe Miller finds his '09 form and we can flip him for a low-level prospect at the deadline. It's the season for optimism right?
