8 and 7) Tom Seaver/Carlos Beltran – 8.2 in 1975 and 2006
Beginning with the greatest Mets pitcher of all-time, the 1975 season was yet another Cy Young season from Seaver. He led the league in wins with 22 and posted a 2.38 ERA. Following an uncharacteristically down year in 1974, Seaver as officially back with an 8.2 WAR season.
Three decades later, Beltran had his best year as a member of the Metropolitans. He tied the franchise record with 41 home runs. His 116 RBI set a new high, too. Armed with a .275/.388/.594 batting line and other excellent totals, it was a dominant year at the plate for one of the franchise’s great outfielders.
6) David Wright – 8.3 in 2007
At number six, we arrive at a finale for this list. David Wright’s 2007 season is currently the best WAR season for any position player in Mets history to lead the team. Even if we include his 8.3 WAR total against players who didn’t lead their team, he’s number one.
Wright’s 2007 season included a career-high in WAR on offense and defense. Combine the two and you get one of the greatest seasons in Mets history which included a fourth-place MVP finish and a Gold Glove.
5) Jon Matlack – 8.7 in 1974
In 1974, Jon Matlack put together one of the best seasons of his career. The lefty starter led the Mets with an outstanding 8.7 WAR. Though he was just 13-15, his 2.41 ERA and league-leading 7 shutouts helped earn him the team-best total.
Matlack’s contributions to the Mets often goes overlooked because of the spotlight he shared with other starters. However, his 1974 season included the first of three All-Star selections and a league-leading 2.42 FIP.
