Marco Scutaro hit a tiebreaking, two-run single in the seventh inning and the San Francisco Giants beat the rival Dodgers 5-2 on Friday night to extend their NL West lead to 51/2 games over Los Angeles.
After Angel Pagan drew an intentional walk from Josh Beckett (1-2) to load the bases, Scutaro followed with a bloop single to shallow right.
San Francisco (78-60) won its fourth straight against Los Angeles after a sweep at Dodger Stadium from Aug. 20-22. The Giants lead the division by 51/2 games for the first time since ending the 2003 season with a 151/2-game cushion. They have two more chances with a sellout home crowd this weekend to create further distance from the Dodgers.
Santiago Casilla (7-5) relieved Tim Lincecum and recorded the final two outs of the seventh for the win.
