World class thoroughbred racing takes place at Saratoga Race Course in Saratoga Springs, N.Y., and on Saturday the late Pick 4 begins with Race 8 at 5:03 p.m. ET and ends with Race 11. Before you make any picks, you NEED to know how racing insider and accomplished horseplayer Bob Weir has handicapped the four-race sequence.

Based in Saratoga Springs, Weir has been handicapping and following horse racing since reading Andy Beyer's landmark handicapping book "Picking Winners" in the late 1980s. Weir is highly invested in the Beyer Speed Figure, a number assigned to every race run by a horse that measures how fast the horse ran. He uses the figure as the backbone of his handicapping. In fact, thanks to his proficiency with speed figures and top-tier handicapping, he landed one of just eight spots on Beyer's figure-making team in 2017, a position he holds to this day.

Weir's methodology has produced multiple five-figure days. In 2014, he hit a $60,000 Pick 6 at Del Mar. The following year, he nailed a $31,000 Pick 6 at Gulfstream Park. In 2016 and 2017, Weir qualified for the prestigious National Horseplayers Championship in Las Vegas. 

Last year, his first for SportsLine, Weir was on fire. In June, Weir hit a $2 superfecta in the Ogden Phipps Stakes that paid a whopping $1,039. He crushed the exacta and trifecta in the Forego Stakes in August for $1,134.50. He hit the late Pick 4 at Belmont Park on June 18, June 19, June 25, July 2 and July 5, with the June 25 score returning a whopping $2,159.50.

This year, he has hit the exacta in the Sam F. Davis Stakes, Tampa Bay Derby and Peter Pan Stakes, the trifecta in the Risen Star Stakes and Blue Grass Stakes and the superfecta in the Belmont Stakes, with the Tampa Bay Derby score returning $1,414! And last weekend he hit the Pick 4 at Saratoga ($163.50) on Saturday and at Del Mar ($594.60) on Sunday.

Those are just some of his scores in 2021.

Now, he has handicapped the late Pick 4 at Saratoga for Saturday, made his picks and constructed his tickets.

We can tell you that Weir is high on Robin Sparkles, the 6-5 favorite in the Caress Stakes, the third leg of the Pick 4. "Robin Sparkles is 5-for-6 in turf sprints, is the clear early speed and, with a good break, could be long gone," Weir tells SportsLine. Robin Sparkles is Weir's top pick in the Caress and a lone A horse on his Pick 4 tickets.

In addition, Weir is high on a double-digit long shot on Saturday! Weir says the "price could be right" on this horse who could spice up the Pick 4. Weir is including this long shot on his tickets, and so should you. You NEED to see Weir's analysis before making any Pick 4 selections.
