#61 is here.
#60 September 21, 1969 Half Up, Nine Left
The Giants were a half dozen games out on July 3, but by August 3 had caught the Braves in the West and then battled for the lead the remainder of the year.
This is game 153, the Giants, who hadn't been in the playoffs since '62, needed to win to maintain a half game lead with 9 to go. They beat the Dodgers 4-3 in 10.
With two out and no one on in the 10th, the Dodgers decided to intentionally walk Willie McCovey; the Giants followed with walks to Bobby Bonds and Ken Henderson - then scored the winning run on an error by Maury Wills.
A three walk+error walk off win against the Dodgers in 10 innings to maintain a half game division lead with 9 to go.
#59 is tomorrow.
