The final prep race for the Kentucky Derby takes place on Saturday when the starting gate opens in the 2023 Lexington Stakes at Keeneland Race Course. The Brad Cox-trained First Mission is the 3-1 favorite in the 2023 Lexington Stakes odds. Disarm, trained by Steve Asmussen, and Arabian Lion, handled by Bob Baffert, are the co-second choices in the 11-horse 2023 Lexington Stakes field, at 7-2. Post time is 5:16 p.m. ET. 

With several lightly raced 3-year-olds 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 2023 Lexington Stakes picks.

A member of the Beyer Speed Figure-making team who is based in Saratoga Springs, N.Y., 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 red-hot in the Triple Crown prep races, hitting the superfecta in the Blue Grass Stakes and exactas in the Fountain of Youth Stakes and Tampa Bay Derby. He also 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. Two weeks ago he hit the late Pick 4 at Gulfstream Park for $641 and the exacta in the Florida Derby.

Now, Weir has handicapped the 2023 Lexington Stakes field, made his picks and constructed his bets.

One surprise: Weir is high on the chances of Prairie Hawk, even though he's a a 15-1 longshot! "Prairie Hawk picks up Hall of Fame jockey John Velazquez and is not without a chance," Weir told SportsLine. Weir is using Prairie Hawk prominently in his wagers.

Moreover, Weir's top pick is a horse who "should be able to get a nice stalking-to-midpack trip" on Saturday. He also is high on a big double-digit longshot who is "bred for the dirt." Weir is including these horses in his 2023 Lexington Stakes bets, and so should you. You ABSOLUTELY need to see his picks before locking in any of your own!
