SAN FRANCISCO (AP) — The catch of his career one night, a three-run homer the next for Nolan Arenado, who put Colorado on the board in the first inning and saw it hold up as the first-place Rockies completed a sweep of the San Francisco Giants with a 4-2 win Wednesday night.

Tyler Matzek (1-0) outpitched two-time NL Cy Young Award winner Tim Lincecum, retiring 12 of 13 batters during one stretch. The NL West-leading Rockies extended the best road start in franchise history to 6-0 while sending the reigning World Series champions to a sixth straight defeat.

Charlie Blackmon added a sacrifice fly for the Rockies, who at 7-2 have matched the best nine-game start in franchise history by joining the 1995, ’97 and 2011 clubs.

Matt Duffy hit his first career home run with a solo drive in the eighth off Boone Logan for the Giants. Angel Pagan added an RBI single in the first.
