The best player in New York Mets history to never appear in a single playoff game for the franchise is also the only guy to throw a no-hitter, Johan Santana.
Johan Santana accomplished quite a lot in his MLB career. Before even joining the New York Mets in 2008, he made four trips to the postseason with the Minnesota Twins and took home a pair of Cy Young Awards.
