DJ LeMahieu belted a go-ahead, two-run home run off Sam Dyson with one out in the top of the ninth inning Thursday afternoon, helping the Colorado Rockies edge the San Francisco Giants 9-8 and avoid a three-game sweep in San Francisco. LeMahieu's heroics came after San Francisco's Alen Hanson had delivered a two-run double off Rockies relief standout Adam Ottavino in the eighth, giving the Giants an 8-7 lead and putting them three outs from a fifth straight win.
