So long, September 1978. The Mets are at least a .500 team over their last 5,872 games, going back to Wednesday, August 30, 1978, an improvement of 3 games. The Mets are at least a .490 team over their last 8,110 games, going back to Saturday, September 26, 1964, an improvement of 1 game. The Mets are at least a .480 team over their last 8,572 games, going back to Saturday, April 28, 1962, an improvement of 5 games. The team's all-time winning percentage is now .4794409, and I'm starting to think an all-time .480 is reachable this season. They would have to go 16-7 the rest of the way. They win tomorrow and their all-time winning percentage would round up to .480.
