Lyles will start the Rockies' home opener Friday against San Diego, Patrick Saunders of the Denver Post reports.
Manager Walt Weiss made the announcement earlier in the week that he'll be employing a four-man rotation to start the year, and Saturday's confirmation on Lyles means that he is officially the number four pitcher in the Rockies' rotation. At Coors Field last season, Lyles went 1-3 with a 4.55 ERA and 1.416 WHIP in five starts. Fortunately, Lyles will be facing a relatively weak Padres lineup in his first start of the season.
