The Phillies own the all time season record with a 466-407 record in the 874 meetings between the two teams. The Phillies are 229-208 at The Polo Grounds (1962-1963), Shea Stadium (1964-2008) and Citi Field (2009-present) and 237-199 at Connie Mack Stadium (1962-1970), Veterans Stadium (1971-2003) and Citizens Bank Park (2003-present). However, the number are a little skewed as neither team has generally been good at the same time. The Mets finished 9th or 10th in the NL in all of their first 7 seasons. When the Mets won the division title in 1969 (the first year of divisional play), the Phillies finished 5th (out of 5). The Mets were the better team until 1974, where both teams finished with a losing record for only the second time (last was 1968). After a close 1975 season, the Phillies were the better team through 1983. The Mets were then the better team from 1984-1990, with both teams finishing with a losing record again in 1991 and 1992. The Phillies won the division and NL Pennant in 1993 but both teams finished with losing records in 1994-1996. The Mets were the better team from 1997-2000 with the Phillies better in 2001 and barely better in 2002 and 2003.
The Phillies were 15 games better in 2004. The most competitive baseball between the Mets and Phillies came from 2005-2008. The Phillies finished in 2nd place in 2005 at 88-74, with the Mets 3rd at 83-79. The Mets won the division in 2006 at 97-65, with the Phillies 2nd at 85-77. 2007 saw the Phillies finish a game ahead of the Mets at 89-73 and 3 games ahead of the 2nd place Mets in 2008 at 92-70. The Mets, of course, have been bad since, making it tough to consider Mets/ Phillies a rivalry.
Since the Mets inception in 1962, the Mets and Phillies have finished 1st and 2nd in the division 4 times, with the Mets winning in 1986 and 2006 and the Phillies in 2007 and 2008. Only 6 times have the Mets and Phillies finished 2 and 3 in the division. Of which, the Phillies finished 2nd (Mets 3) in 1975, 2001 and 2005 and the Mets finished 2nd (Phillies 3) in 1999 and 1999. During the shortened 1995 season, the Mets and Phillies finished 2nd with the same record of 69-75.
