In advance of putting single-game tickets on sale starting Nov. 18, the Mets on Monday announced their promotional schedule for 2017, highlighted by Noah Syndergaard Hair Hat Day against the Marlins on May 6.

The team is bringing back its Free Shirt Friday promotion on 13 Fridays, including a long-sleeved T-shirt for an April 7 game against the Marlins, when long sleeves presumably will come in handy.

In addition to the Syndergaard Hair Hat, Saturday promotions include an Asdrubal Cabrera bobblehead against the Phillies on July 1 and a garden gnome against the Nationals on April 22 featuring a player yet to be announced. (So, maybe Yoenis Cespedes, or maybe not.)

Sunday promotions start with rally towels against the Marlins on April 9 and end with 2018 schedule magnets against the Nationals on Sept. 24. 2018.
