Watch: Arenado passes Story with league-leading 11th HR

Your move, rook.

Tied with teammate Trevor Story for the MLB lead with 10 home runs heading into Sunday's series finale, Colorado Rockies third baseman Nolan Arenado surged past the precocious rookie and grabbed sole possession of first place with a seventh-inning blast off Arizona Diamondbacks right-hander Randall Delgado.

Through the first month of the season, Arenado and Story have combined for five more home runs than the next-most prolific pair of teammates, Neil Walker and Yoenis Cespedes of the New York Mets, who have slugged a combined 16 homers so far.
