Monday’s Mets-Dodgers game at Citi Field was postponed due to rain.

It will be made up Tuesday as part of a single-admission doubleheader, beginning at 4:10 p.m.

Tickets for Monday’s game won’t be valid for the doubleheader, and ticket-holders will receive a voucher for a ticket to a different game.

Tylor Megill was scheduled to start Monday for the Mets against the Dodgers’ Gavin Stone.

The Mets (22-30) avoided a second straight sweep on Sunday with a three-run ninth-inning rally to defeat the Giants, capped off by Omar Narvaez’s walk-off single.
