Jeremy Hefner is enjoying his new life in the NL East.

Access the Mets beat like never before

Don’t miss Mike Puma’s text messages from Queens and beyond — he’s giving Sports+ subscribers the inside buzz on the Mets.

Fired as Mets pitching coach after last season, Hefner will return to Citi Field on Friday with a Braves team that owns MLB’s best record. Much of the club’s success stems from a pitching staff overseen by Hefner that, as of Thursday, held an MLB-best 3.20 ERA.

Hefner isn’t looking back (too much), but told Sports+ on Thursday that he was as culpable as anyone for the pitching staff’s free fall last season that played the largest factor in the Mets missing the playoffs.

Kodai Senga, David Peterson and Sean Manaea all floundered after the All-Star break following a pitching surge that carried the Mets into late June.
