The showdown at Belmont Park has become a two-horse race.

Blumenfeld Development Group Monday announced it was withdrawing from the bidding to build at the race track in Elmont, N.Y., Newsday reported.

That left only two bidders — the New York Islanders hockey team and New York City FC.

Blumenfeld said the bidding process was no longer an “effective use of BDG resources,” according to Newsday.

The remaining bidders will take part in a listening session as they will discuss their Belmont ideas at Elmont Memorial High School Sunday at 4:30 p.m.

On Sept. 28, NYCFC, which has called Yankee Stadium home since joining Major League Soccer as an expansion team in 2015, put in a bid for Belmont that includes a recreational area for fans outside the stadium. A retail component reportedly also is being proposed by Related Cos., a Manhattan-based developer.

The soccer club has expressed interest in three other locations — the Harlem River Yards in the South Bronx and a spot near the stadium and in Flushing, according to Newsday.

City became the second soccer team to bid Belmont as the Cosmos (North American Soccer League) placed a proposal in January 2013 before the ESDC and waited for three years before it asked them and other bidders to resubmit their proposals.

Some residents want a third candidate in the race, even though it is well after the Sept. 28 deadline.

On Sunday, more than two dozen citizens got together in Elmont, asking Amazon to bring its second headquarters to the race track area, Newsday reported.

More than two dozen people gathered in Elmont on Sunday to call for Amazon to bring its second headquarters to Belmont Park.

Nassau County Legislator Carrie Solages (D-Elmont) told Newsday that his office and other levels of government “are all actively pursuing this site as a possibility for that development.”
