The Reds have designated Aaron Miles and Wladimir Balentien for assignment, according to C. Trent Rosecrans of CNati.com (Twitter link). We heard on the weekend that the Reds were likely to designate the pair for assignment to create roster space if GM Walt Jocketty didn't find a trade partner.
The Mariners designated Balentien for assignment last summer, before the Reds acquired the outfielder leading up to the trade deadline. The Reds would acquire Miles six months later for Adam Rosales and Willy Taveras in a bad contract swap.
Miles hit .185/.224/.242 in 170 plate appearances for the Cubs last year and followed that up with a .152/.222/.212 performance this spring. It's hard to imagine any team claiming him. Balentien hit a more robust .327/.353/.571 this spring; in 295 plate appearances last year, he hit .234/.305/.385.
