The Mark Casse-trained Nitrogen can solidify herself as the top 3-year-old turf filly in the country when she leaves the starting gate in the 2025 Belmont Oaks Invitational Stakes on Sunday at Saratoga Race Course in upstate New York. The daughter of Medaglia d'Oro has five wins in eight career starts. She is coming off a 17-length romp in the Wonder Again Stakes on the Belmont Stakes undercard. For Saturday Nitrogen has been installed as the 4-5 morning-line favorite in the 2025 Belmont Oaks Invitational Stakes odds. Fionn (5-1), Totally Justified (6-1), Warming (8-1) and Virgin Colada (8-1) round out the top five choices among the seven 2025 Belmont Oaks Invitational Stakes horses. Post time for the Grade 1 race is 6:13 p.m. ET.

With several talented horses set to enter the starting gate on Saturday, you NEED to see what SportsLine horse racing expert Gene Menez has to say before making any 2025 Belmont Oaks Invitational Stakes picks or horse racing predictions, considering the roll he has been on since November.

A former reporter and editor at Sports Illustrated, Menez covered an array of sports, including horse racing, for the magazine and its website for almost 14 years. Between 2010 and 2012, he served as SI's handicapper for the Triple Crown races and correctly predicted Super Saver to win the Kentucky Derby in 2010.

In 2015, Menez accurately gave out the Kentucky Derby superfecta, which paid $1,268.20 for $2. In 2017, he tweeted out his Kentucky Derby picks, including Always Dreaming to win, and hit the Pick 4, which paid almost $6,900 on a $1 bet. In May of last year, Menez gave out 18-1 Mystik Dan as a live longshot in the Kentucky Derby. Unlock his 2025 Belmont Oaks Invitational Stakes picks now and take 50% off with promo code JOCKEY.

Menez has been on a roll since November. He crushed the late Pick 4 on Breeders' Cup Saturday for a $5,303 windfall. He nailed the winner, trifecta and superfecta in the Florida Derby for a $529.60 score and the winner and trifecta in the Blue Grass Stakes for a $761.96 jackpot. Hit the late Pick 4 on Kentucky Oaks day for $915.48. And in the Kentucky Derby, he hammered the exacta and trifecta for a $1,045 payout.

Now, Menez has handicapped the 2025 Belmont Oaks Invitational Stakes field and revealed his picks. We can tell you that Menez's top pick is not Nitrogen, even though she is the 4-5 favorite. "She's the best 3-year-old turf filly in the country, but she has had just four weeks rest since a huge effort in the Wonder Again Stakes," Menez told SportsLine. Join SportsLine NOW to unlock his full 2025 Belmont Oaks Invitational Stakes picks for 50% off with promo code JOCKEY.
