Blackmon will start in center field and bat leadoff Sunday against the Marlins, Patrick Saunders of the Denver Post reports. Blackmon was absent from Saturday's lineup against a right-handed pitcher, but Rockies fans can now exhale, as it appears to have been a routine day off. The left-handed Blackmon is putting together his best month of the season in terms of batting average (.302), but has just two extra-base hits so far in June.
