#64 is
here.
#63 September 3, 1978
Through 135 games, the furthest the Giants had been out of first was 4.5 games (and that was only once) and their greatest division lead was 3 games. San Francisco was down 2.5 coming into a doubleheader against the Phillies - and after a sweep, trailed only by 1 with 25 left to play.
Bob Kenpper threw a complete game 1, striking out 9 and walking just one. In game two, down 2-1 in the 8th inning, Hector Cruz hit a two out, two strike, two run single to give the Giants a 3-2 lead that would be the final score.
