4) Billy Wagner
5-5, 101 SV, 2.37 ERA, 230 SO, 183 ERA+, 2.87 FIP, 1.054 WHIP, 5.0 WAR
Billy Wagner was an excellent closer throughout his career, and should be in the Hall of Fame. He continued to have success upon joining the Mets. He was a two-time All-Star twice and finished sixth in NL Cy Young voting in 2006.
He did have his fair share of inconsistencies and injuries, but he was also lights-out at various points of his Mets tenure and was instrumental in helping the Mets win the division for the first time in 18 years in 2006. “Billy the Kid” led the team in saves from 2006 to 2008.
3) R.A. Dickey
39-28, 2.95 ERA, 468 SO, 129 ERA+, 3.55 FIP, 1.150 WHIP, 12.9 WAR
R.A. Dickey wasn’t in New York for very long, but he was great while he was there. In 2012, he was named as an All-Star and won the NL Cy Young Award.
During that season, he joined legends Sandy Koufax and Nolan Ryan as the only pitchers to pitch two complete game one-hitters with 12 or more strikeouts in one season. He’s also the only pitcher to do so in back-to-back starts.
Dickey led the Mets in innings pitched in 2011 and 2012. In 2012, he led the team in wins, strikeouts, and games started and threw five complete games and three shutouts.
He led the team in ERA throughout his entire tenure in New York. During his Cy Young season, he led the NL in games started, complete games, shutouts, innings pitched, strikeouts, and batters faced.
