SAN FRANCISCO, CA (AP) -- Zach Cozart delivered a tie-breaking, two-run single in a 5-run 11th inning to help Cincinnati top the Giants 7-3.
Chris Heisey tripled in two more runs in the rally to lead the Reds to their fourth straight win.
The Giants had held the Reds scoreless over the first eight innings of the contest, and held a 1-0 advantage before Sergio Romo walked Joey Votto to start the ninth. Brandon Phillips followed by launching a blast into the seats in left-center.
The NL West-leading Giants have dropped three in a row and eight of 11.
