Who has the Lowest ERA for the Mets?

For generations Earned Run Average (ERA) has been used to measure a pitcher’s effectiveness. While more recently ERA+ and Fielding Independent Pitching (FIP) have gained favor. Both attempt to remove the effects of external factors like ballparks, opponents or fielding to “normalize” the statistic.

But let’s stay old-school and look at pitcher’s ERA. Who is atop the leader board for the best ERA for the Mets in a single season?

If there were any justice in the world, Dwight Gooden would wear the single-season Mets ERA crown. In 1985 Gooden pitched an NL leading 276 innings, going 24-7. His 1.53 ERA also led the league that year. As did his 16 complete games, 268 strikeouts, 229 ERA+, and 2.13 FIP. He was the unanimous winner of the Cy Young award.

Pitchers, especially relievers, can have one great year followed by a fall into obscurity. So what about over an entire Mets career? Who has the best ERA in a Mets career?
