Ryan Roberts, designated for assignment earlier in the day on Tuesday, was traded to Tampa Bay for Minor League infielder Tyler Bortnick. Roberts struggled this season, hitting .250. He was a big part of Arizona's surprising postseason run a year ago with 19 homers and 65 RBIs. "I don't know if we would have won the division without what he was able to do on the field both defensively, offensively and on the basepaths," GM Kevin Towers said. "I'm going to miss the way he played the game. He played with a lot of enthusiasm, energy and fire." Bortnick, 25, is hitting .253 with 48 RBIs for Double-A Montgomery. Rockies: Giambi to disabled list
Veteran Jason Giambi was placed on the 15-day disabled list, retroactive to July 21, with viral syndrome. Giambi -- who manager Jim Tracy says is experiencing body weakness -- is hitting .241 with four doubles and one homer.
Rockies catcher Wilin Rosario returned to the lineup Tuesday after missing three games, going hitless in three at-bats.
