 Although both teams each won a World Series in the 1980s, the Mets were not serious contenders in the Phillies' playoff years (1980, 1981, and 1983), nor did the Phillies seriously contend in the Mets' playoff years (1986 and 1988).The Mets were the Majors' worst team when the Phillies won the NL pennant in 1993, and the Phillies could not post a winning record in either of the Mets' wild-card-winning seasons of 1999 or 2000, when the Mets faced the New York Yankees in the 2000 World Series.The rivalry intensified in the mid 2000s, as the teams battled more often for playoff position.
