Top thoroughbred racing takes place at Belmont Park in Elmont, N.Y., and on Saturday the late Pick 4 at Belmont begins with Race 8 at 4:38 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, N.Y., 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.

And this year he has hit the exacta in the Sam F. Davis Stakes and Tampa Bay Derby and the trifecta in the Risen Star Stakes and Blue Grass Stakes, with the Tampa Bay Derby score returning $1,414! Those are just some of his scores in 2021.

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

We can tell you that Weir is high on Third Draft, the 3-1 second choice in Race 11, the last leg of the Pick 4. "She could be poised to step forward," Weir tells SportsLine. Third Draft is Weir's top pick in Race 11 and an A horse on his Pick 4 tickets.

In addition, Weir's top pick in one of the races is a double-digit long shot! Weir says this horse "can only improve" and 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.

So which double-digit long shot can win? And how has Weir constructed his Pick 4 tickets? ... Join SportsLine now to get late Pick 4 selections at Belmont for Saturday, all from the racing insider who has been on fire!
