Rainout fears over Derek Jeter's final game at Yankee Stadium drive down ticket prices

A rainout for Derek Jeter’s mega-hyped Bronx farewell would give ticket brokers a multimillion-dollar bath — and leave some unlucky fans feeling all wet, too.

If Mother Nature delivers the predicted wet and windy Thursday weather, secondary market sellers could lose about $12.5 million on the Captain’s last game in Yankee Stadium, according to one expert.

“It would be a disaster for brokers if this game is rained out and never made up,” said Connor Gregoire of SeatGeek.com.

“Brokers will lose all the profits they would have otherwise made on this, the most expensive regular season ticket in MLB history.”

Gregoire noted that roughly 30,000 tickets were resold — some more than once — since Jeter announced his retirement in February.

The average price of those tickets was $415 — although the figure grew as it became clear the Yankees were not making the playoffs and this would be Jeter’s final home game as an active player.

The ticket brokers will have to return all that money if the game between the playoff-bound Orioles and the disappointing Bronx Bombers is canceled.

“Real, live profits are going down the drain for them,” said Chris Matcovich of TiqIQ.com. “They would have to refund all the money. Hopefully they have it in escrow.”

It’s unlikely the Yankees-Orioles game would ever be made up if rained out — and the forecast is ominous.

Rain was possible beginning early Thursday around midnight and likely throughout the day, with showers expected right up until the first pitch at 7:05 p.m. Rain remained a possibility until midnight.

Winds of 14 to 18 mph were expected to make it feel colder than the predicted 62 degrees at the start of the game on a fall night in the South Bronx.

The Yankees released no weather contingency plan, and appear bent at all costs on making sure Jeter’s grand finale is played — weather or not.

Fans who purchased their tickets through Craigslist or illegitimate scalpers will possibly be crying in their beers instead of cheering for Jeter.

“If folks purchased their tickets privately or on Craigslist, they’re stuck trying to track down their seller with no guarantee of a seller and no official recourse,” Gregoire said.

There were 1,414 tickets available on StubHub about 24 hours before Thursday’s first pitch, with the priciest seat going for $15,225.

The cheapest seat was a single left field bleacher ticket priced at $225. And the asking price for seats behind the Yankees dugout, set at $9,711 each on Tuesday, were down to $5,502 by Wednesday.
