The Colorado Rockies set a Major League record last season for consecutive losses in Sunday games. They’re off on the wrong foot on Sundays this season as well. The Rockies fell to the Arizona Diamondbacks 5-2 at Coors Field yesterday afternoon, failing to complete the home sweep of the defending NL West division champs. Rockies starting pitcher Drew Pomeranz struggled in his season debut. The young southpaw allowed five runs in four and two-thirds innings to take the loss. Troy Tulowitzki and Tyler Colvin drove in a run for the Rockies in the losing effort. The Rockies are 4-5 on the season and 0-2 on Sundays. They begin a three-game series against the San Diego Padres in Denver tonight. ESPN Radio 1410 will have the action, with pregame coverage at 7:05 and the first pitch at 7:40.
