The 1973 National League Championship Series was played between the New York Mets and the Cincinnati Reds from October 6 to 10. New York won the series three games to two and advanced to the World Series, where they lost to the Oakland Athletics in what was the second of three straight world championships for Oakland. The Mets set a record for lowest win percentage by a pennant winner, finishing the regular season with an 82–79 record. However, most of the season was plagued by the injury jinx to their key players. In September they finally got healthy and just in time for the playoffs. The Mets' victory has gone down as one of the greatest upsets in MLB history, as they dominated the heavily favored Big Red Machine.
