The Colorado Rockies have designated 34-year old righty swinging catcher Wil Nieves for assignment. He played in 16 games for the Rockies this year and he was 14 of 47 (.298 avg, .738 OPS) with 3 runs scored, 1 homer and 5 RBIs. Nieves has now played in 298 games in his first 9 years in the majors and he is 180 of 798 (.226 avg, .568 OPS) with 58 runs scored, 6 homers, 78 RBIs and 2 stolen bases. The Rockies probably would like to keep Nieves around if he clears waivers and is willing to accept a outright assignment to the minors, just in case they find a taker on the trade market for Ramon Hernandez.
UPDATE: (8/4/2012) - Wil Nieves has rejected an outright assignment to the minors and he has become a free agent.
