Didn't Brayan Pena request his release in order to join the military or did I make that up? We have Corporan, Solis, Davis and soon Caratini in AAA as catchers. This is a good website for our depth chart: http://www.rosterresource.com/mlb-chicago-cubs/ Our MI and 1B depth in the upper minors could use help, so someone like Ackley, Coghlan or Kelly Johnson would be good on a minor league deal. Our relief corps is pretty deep. In addition to the guys in the majors, also have Rosario, Black, Leatherstich, Acevedo, Concepcion, Pena, Rollins, Parra and Rosscup, in addition to newbies Conor Mullee (good in AAA last year for the Yanks), Fernando Rodriguez (who has been a decent middle reliever the past couple years), Daniel Corcino, Maikel Cleto, and others. The SP depth has been discussed and definitely improved the past few days with Kelly and Butler.
