They did play about 500 ball over the last 100 games last year. With the right player or two added this offseason 80+ wins is very realistic there. Once you get to that all it takes is a few breaks to be playing October baseball. Giants won 88 this season. From a .500 club that is about 1 extra win a month.
As a Mets fan I am watching what they are doing and wondering when my guys will finally realize that is the way to do business.
