No lead is safe for the Mets these days.

Not even for their high-powered, new-look bullpen.

Tyler Rogers faltered and Ryan Helsley relinquished a lead in Thursday night’s 4-3 loss to the Atlanta Braves at Citi Field, dealing the Mets their 13th loss in 15 games.

Helsley surrendered a pair of runs in the eighth inning, including Ozzie Albies’ go-ahead RBI double that proved to be the game-winner.

Boos rained down from a crowd of 41,782 as the fourth-place Braves (53-68) clinched yet another series victory over the Mets (64-57).

The score was tied, 1-1, when Mets starter Kodai Senga exited after 93 pitches with two outs and runners at the corners in the top of the sixth.

Rogers relieved him and promptly surrendered an RBI single to Albies, giving Atlanta a one-run advantage.
