Saturday is Kentucky Derby day at Churchill Downs in Louisville, Ky., and there's a Pick 4 that begins with the American Turf Stakes at 3:40 p.m. ET and ends with the Kentucky Derby. 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 five weeks ago.

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.

For Kentucky Derby Saturday, Weir has handicapped the Pick 4 at Churchill Downs, made his picks and constructed his tickets.

We can tell you that Weir is high on Legend of Time, the 7-2 favorite in the American Turf Stakes, the opening leg of the Pick 4. "This does not appear to be the strongest group of U.S. 3-year-old turfers, so Legend of Time may hold a real advantage," Weir told SportsLine. Legend of Time is Weir's top pick in the American Turf Stakes and an A horse on his Pick 4 tickets.

In addition, Weir is high on a double-digit longshot on Saturday. He says this longshot is a "proven late runner" 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? ...
