DENVER -- The Rockies reinstated veteran backup catcher Wil Nieves from the disabled list on Wednesday and then designated him for assignment, meaning they have to expose him to other clubs via waivers, and have 10 days to decide whether outright him to the Minors, trade him or release him. Nieves, 34, began this season at Triple-A Colorado Springs before being called up to the Rockies in late May. He hit .298 with a home run, two doubles and five RBIs in 16 games as backup to rookie Wilin Rosario while Ramon Hernandez was out with a left hand injury. However, the Rockies placed Nieves on the 15-day DL on July 13 with turf toe in his right foot. Nieves has played in the Majors with the Padres (2002), Yankees (2005-07), Nationals (2008-10), Brewers (2011) and Rockies (2012), and has hit .226 with six home runs, 34 doubles and 77 RBIs in 298 games.
