The Cubs were favorites to win the NL East in 1969. But the impossible happened. The Cubs were in 1st all year long, but out of nowhere came the New York Mets. By late August the Mets had snuck up on the Cubs and were 2 games back. On September 9 Tom Seaver gave the Cubs their 6th straight loss, giving the Mets a sweep of 2 games. New York now trailed the Cubs by one-half game. The very next day, Ken Boswell's 12th-inning single scores Cleon Jones, and the Mets beat the Expos 3-2 in the first game of a doubleheader. The win puts the Mets in the top spot for the first time in club history. The Cubs' loss drops them out of first after 155 days atop the NL. The Cubs continued to blow and finished the month of September with a 9-17 record. The Mets held on to first place and won the East. They went on to win the World Series.
