With their pitching staff under siege by injuries, the Mets worked the trade market for relief.

The Mets acquired Wilmer Font from the Rays on Monday for a player to be named later, The Post’s Joel Sherman confirmed.

With relievers Jeurys Familia (shoulder soreness), Luis Avilan (elbow soreness) and Justin Wilson (elbow soreness) all on the injured list, and starters Steven Matz (nerve irritation) and Jason Vargas (hamstring) potentially joining them there, Font will provide depth and versatility.

The 28-year-old righty had a 5.79 ERA in 10 appearances with the Rays this season — four of which were multi-inning outings — while striking out 18 and walking five.

Font also started five games for the Rays last season after being traded by the Dodgers and A’s earlier in the year. His season was cut short by a lat strain in June.

With a career 6.51 ERA across 37 games in the majors, Font was out of options and could not be sent to the minors without going through waivers, Sherman reported, opening the door to a trade with the Mets.
