Some view the wild-card games as an extension of the regular season, but Wednesday night’s showdown at Citi Field between the Mets and Giants is as costly as a playoff game, if not more so.

As of Monday afternoon, second-hand tickets for the elimination game, featuring a pitching showdown between Noah Syndergaard of the Mets and Madison Bumgarner of the Giants, cost an average of $314.01, the most expensive wild-card game ever, according to TicketIQ, a ticket-search site. Last year’s National League wild-card game, between the Cubs and Pirates in Pittsburgh, was the second-most pricey at an average of $264.68.

Both far surpass the average price of the Yankees’ wild-card game last year against the Astros, which was just $174.83 a ticket. Even standing-room-only tickets are expensive at $162 a pop. The most expensive seat is in Delta Platinum Row 2 at more than $3,500.

“That people are willing to stand, to pay $162 to stand, kind of speaks for itself,” said Chris Matcovich of TicketIQ.
