Mac Williamson homered in the fifth inning and hit a tiebreaking single in the 12th, lifting San Francisco over the New York Yankees 2-1 Saturday for the Giants' first victory since the All-Star break.
NL West-leading San Francisco had lost a season-high six straight games and had held just one lead since the break: when Buster Posey hit a go-ahead home run leading off the 10th inning at San Diego on July 16 only to have the Padres rally for a pair of runs in the bottom half against Santiago Casilla.
Williamson, whose fourth-inning error allowed the Yankees' run, began the comeback when he connected off Ivan Nova leading off the fifth.
Trevor Brown hit an opposite-field double to right off Anthony Swarzak (1-1) leading off the 12th, and Williamson singled up the middle with one out, just past the glove of diving shortstop Didi Gregorius. San Francisco was 0 for 10 with runners in scoring position, dropping to 7 for 64 (.111) since the All-Star break, before Williamson's single.
