The biggest two days in horse racing takes place this week with the 2023 Breeders' Cup at Santa Anita Park in Arcadia, Calif., and on Friday the late Pick 4 begins with the Juvenile Fillies at 5:40 p.m. ET and ends with the Juvenile Turf. Before you make any picks, you NEED to know how Saratoga Springs-based racing insider and Beyer Speed Figure maker Bob Weir has handicapped the sequence.

A member of the Beyer Speed Figure-making team, 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 for $1,678 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.

In April of this year, he hit a Pick 4 at Gulfstream Park for $641, the exacta in the Florida Derby, a Pick 5 at Keeneland and the exacta in the Lexington Stakes. He smashed the trifecta in the Belmont Stakes for $532.96, and later in June he crushed the Pick 4 at Belmont for $555. Those are just some of his scores this year.

For Friday, Weir has handicapped the late Pick 4 at Santa Anita, made his picks and constructed his tickets.

We can tell you that Weir is high on Tamara, the 4-5 favorite in the Juvenile Fillies, the opening leg of the Pick 4. "There are some questions with her going two turns for the first time, but her win in the Del Mar Debutante at seven furlongs was impressive both visually and on the clock," Weir told SportsLine. Tamara is Weir's top pick in the Juvenile Fillies and a lone A horse on his Pick 4 tickets.

In addition, Weir is high on a big double-digit longshot on Friday. Weir says this longshot "could be interesting at a big price" and could spice up the Pick 4. Weir is including this longshot on his tickets, and so should you. You NEED to see Weir's analysis before making any Pick 4 selections.
