Cubs RHP Silva leaves in bottom of first inning

DENVER -- Right-hander Carlos Silva has left the Chicago Cubs' game against the Colorado Rockies in the first inning with an illness.

A Cubs trainer went to the mound after Silva walked the second batter he faced, Jonathan Herrera. Silva remained in Sunday's game and allowed a single to Carlos Gonzalez and a ground-rule RBI double to Troy Tulowitzki.

Acting manager Alan Trammell and the trainer went back to the mound, and Silva was replaced by left-hander James Russell.

Silva allowed two runs in 1-3 of an inning, his shortest start of the season.
