Melville will be making his fourth start on the road. He is 2-0 as a visitor since joining the Rockies on Aug. 21, having allowed one run in seven innings at Arizona in his Rockies debut -- which was exactly two years from his previous big-league appearance. He also earned a win at San Diego on Sept. 6, allowing two runs and striking out a career-high eight in 5 2/3 innings.
