This would be an enormous … enormous win.

WFAN host Mike Francesa’s horse Mongo Nation, named for his faithful listeners and unofficial fan club, will make his anticipated debut in Wednesday’s sixth race at Saratoga.

Trained by David Fawkes for JEH Racing; the two-year-old colt arrived at the Spa late last month and has put in four works; two of which were outstanding. He’s sired by Breeders’ Cup sprint champion Speightstown and drew the hedge as well as the services of the always dangerous rider Joe Bravo.

Tough spot for an opener, and he will be priced accordingly. Morning line is 12-1. Post time, Mongo Nation, is set for 3:48 p.m. — so no further calls, please.

Francesa also owns House Of Friends, who broke his maiden earlier in the meet. He will look to make it two in a row in Wednesday’s fourth race, tackling claimers for Hall of Fame trainer Billy Mott.
