Saturday is Preakness Stakes day at Pimlico Race Course in Baltimore, Md., and the late Pick 4 at Pimlico begins with Race 10 at 4:05 p.m. ET and ends with the Preakness. 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 Pimlico for Saturday, made his picks and constructed his tickets.

We can tell you that Weir is high on Laki, a 6-1 shot in the Maryland Sprint Match Series Stakes, the second leg of the Pick 4. "He's always competitive at this level and draws inside, and if he's able to work out a rail-skimming stalking trip he could be the right one," Weir tells SportsLine. Laki is Weir's top pick in the Maryland Sprint and an A horse on his Pick 4 tickets.

In addition, Weir is high on a double-digit long shot on Saturday! Weir says this horse "could surprise at a fair price" 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.
