SCOTTSDALE, Ariz. -- Welington Castillo hit a solo home run in the fourth inning as the Arizona Diamondbacks defeated the Colorado Rockies 6-3 in their Cactus League opener on Wednesday.

Nolan Arenado, who led the majors with 130 RBIs last season, doubled in a run in his first at-bat of the spring for the Rockies, who scored twice in the first inning off of Rubby De La Rosa.

De La Rosa gave up two runs and three hits in two innings. Archie Bradley followed him to the mound and pitched two scoreless innings.
