World class horse racing takes place at Churchill Downs in Louisville, Ky., and on Sunday the late Pick 4 begins with Race 7 at 3:50 p.m. ET and ends with Race 10. 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 since 2017, 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 and an $18,000 Pick 5 at Tampa Bay Downs in early April.

In April of last 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 a Pick 4 at Belmont for $555. Those were just some of his scores for SportsLine from 2023.

And just last weekend, Weir hit the exacta in the Churchill Downs Stakes for $852.

For Sunday, Weir has handicapped the late Pick 4 at Churchill, made his picks and constructed his tickets.

We can tell you that Weir is high on Dissolved, a 5-1 shot in Race 9, the third leg of the Pick 4. "This Mike Maker-trained 4-year-old will get his first chance over turf and looks made for it," Weir told SportsLine. Dissolved is Weir's top pick in Race 9 and an A horse on his Pick 4 tickets.

In addition, Weir is high on a double-digit longshot on Sunday. He says this longshot "has been working well" 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.

So which double-digit longshot can win? And how has Weir constructed his Pick 4 tickets? ... Join SportsLine now to get Pick 4 selections at Churchill for Sunday, all from the horse racing insider who has had multiple five-figure days at the track and just hit an $18,000 payday!
