Hunter Pence drove in three runs with a pair of doubles Sunday and the San Francisco Giants completed a three-game sweep with an 8-3 win over Colorado. Marco Scutaro supplied a two-run double, while Buster Posey went 2-for-4 with a run-scoring single for the Giants, who outscored the Rockies 33-13 in the series. Tim Lincecum (6-11) recorded a second consecutive win for the first time since April, holding the Rockies to one run on five hits over six frames. The right-hander overcame five walks and struck out three. The National League West-leading Giants came into the contest with a half-game lead over the second-place Los Angeles Dodgers. Colorado starter Tyler Chatwood (1-2) lasted just 3 1/3 innings, handing out four bases-on-balls while allowing three runs (one earned) on two hits. Carlos Gonzalez and Jordan Pacheco each had two hits and an RBI for the Rockies.
