Although the Mets suffered many blows to their cadre of long relievers, swingmen, and mop-up guys in 2021 due to injury, the back end of the Mets’ bullpen that handled innings six and seven and onward stayed remarkably healthy. The Mets had five qualified relievers in 2021: Edwin Díaz (62 2⁄3 IP), Trevor May (62 2⁄3 IP), Jeurys Familia (59 1⁄3 IP), Aaron Loup (53 2⁄3 IP), and Miguel Castro, who let the pack in innings pitched with 68 1⁄3 innings in 2021.
