Cubs Designate Eduardo Sanchez For Assignment

The Cubs have designated right-handed reliever Eduardo Sanchez for assignment, tweets Bruce Miles of the Daily Herald. With the move, the team cleared a 40-man roster spot for Ryan Sweeney's activation from the 60-day DL.

Sanchez, now 24, registered a 1.80 ERA (and notched five saves) in 30 innings for the Cardinals back in 2011. Yet with durability already one of his biggest concerns, a series of injury issues and a poor 2012-13 performance record left Sanchez to be claimed off of waivers by the Cubs earlier this year. Since switching organizations, Sanchez has struggled to a 5.68 ERA in 6 1/3 big league innings while walking as many as he has struck out. Across 40 Triple-A innings this season with Chicago and St. Louis, Sanchez has a 3.38 ERA, but has done so with a troubling strikeout-to-walk ratio (7.9 K/9 versus 5.2 BB/9).
