DENVER - Tyler Chatwood threw into the sixth inning and Wilin Rosario hit a two-run homer off Tim Lincecum in the Colorado Rockies' 10-2 rout of the San Francisco Giants on Saturday night.
Chatwood (2-0) had a shaky second inning but settled in after that and handcuffed the Giants, who managed one run and six hits in 52/3 innings.
Rosario made a nifty defensive play to thwart a big second inning and drove in three runs for the Rockies, who beat the Giants for the second straight time after snapping a 10-game losing streak to them one night earlier, ending their longest streak over a division opponent since divisional play began in 1969.
Lincecum (3-3) committed a costly throwing error that led to a three-run third inning and also had a balk that led to another run in the fourth before Rosario took him deep in the fifth.
Josh Outman threw two effective innings of relief and Wilton Lopez got the final four outs.
