DENVER (AP) - Nolan Arenado hit a two-run double off the wall in the ninth inning, lifting the Colorado Rockies to a 5-4 win over the San Francisco Giants on Tuesday night.
It's the second straight game the Rockies have won in walkoff fashion, with Justin Morneau hitting a two-run homer in the 10th against San Diego on Sunday.
The NL West-leading Giants took a 4-3 lead in the top of the ninth on an RBI double by Tyler Colvin against closer LaTroy Hawkins (2-0).
Arenado hit a 2-2 pitch off closer Sergio Romo (3-1) that glanced off the top of the fence in left and bounced back into the outfield, easily scoring Troy Tulowitzki and then a hustling Carlos Gonzalez with the winning run.
