Trainer Aidan O'Brien will try to win the Belmont Derby for the second straight year when he sends out the favored Stone Age in the 2022 Belmont Derby on Saturday at Belmont Park in Elmont, N.Y. O'Brien won last year's Derby with Bolshoi Ballet. This year's race has attracted an even stronger field, led by Stone Age, who has won two of three starts this year. He has been installed as the lukewarm 9-2 morning-line favorite in the Belmont Derby odds. The Charlie Appleby-trained Nations Pride is the 5-1 second choice in the wide-open, 13-horse Belmont Derby field. Post time is 5:12 p.m. ET. 

With an accomplished field set to enter the starting gate on Saturday, you'll want to see what racing insider and Beyer Speed Figure maker Bob Weir has to say before making any Belmont Derby picks.

With an accomplished field set to enter the starting gate on Saturday, you'll want to see what racing insider and Beyer Speed Figure maker Bob Weir has to say before making any Belmont Derby picks.

A Saratoga Springs-based racing insider and Beyer Speed Figure maker, Weir is a two-time qualifier for the prestigious National Horseplayers Championship in Las Vegas. He has produced multiple five-figure days at the track over the years, including a $60,000 Pick 6 at Del Mar in 2014. Last year, he was on fire. He hit the exacta in the Sam F. Davis Stakes, Tampa Bay Derby and Peter Pan Stakes, the trifecta in the Risen Star Stakes, Blue Grass Stakes and Pennsylvania Derby and the superfecta in the Belmont Stakes.

This year, he has been red-hot in the Triple Crown prep races, hitting the superfecta in the Blue Grass Stakes, the trifecta in the Louisiana Derby and exactas in the Fountain of Youth Stakes and Tampa Bay Derby. He also has hit the 19-1 winner of the Man o' War Stakes, the trifecta in the Pegasus World Cup, the superfecta in the Met Mile and multiple Pick 4s, including May 14's at Belmont for $1,851. One week ago he hit the 6-1 winner of the Mother Goose Stakes and the Pick 4 at Belmont Park. Anyone who has followed him is way up.

Now, Weir has handicapped the 2022 Belmont Derby Stakes field, made his picks and constructed his bets.

One surprise: Weir is high on the chances of Tiz the Bomb, who is the co-third choice on the morning line, at 6-1. "If he's improved [from age 2 to 3], the move back to the right surface could make all the difference," Weir says. He is using Tiz the Bomb prominently in all of his wagers.

Moreover, Weir's top pick is a horse who "has been brought along slowly." Weir also is high on a double-digit long shot who "could get forgotten on the board." Weir is including these horses in his 2022 Belmont Derby bets, and so should you. You ABSOLUTELY need to see his picks before locking in any of your own!
