According to MLB.com, the Rockies designated right-hander Adam Eaton for assignment in order to clear 40-man roster space for infielder Mike McCoy.
Eaton, 31, posted a 5.63 ERA in eight innings of relief for the Rockies back in August shortly after inking a minor league deal. He was also released by the Orioles earlier this season and will finish the 2009 campaign with an 8.08 ERA in 49 innings (eight starts).
