Saturday is the signature day of the year at the Fair Grounds in New Orleans, and the late Pick 4 begins with Race 11 at 5:12 p.m. ET and ends with Race 14. 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 two weeks ago, he crushed the exacta in the Tampa Bay Derby for $1,414! Anyone who has followed Weir is way up.

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

We can tell you that Weir is high on Roadster, the 3-1 second choice in the New Orleans Classic Stakes, the opening leg of the Pick 4. "This is a tough ask off the long layoff, but he seems to be working well," Weir tells SportsLine. Roadster is Weir's top pick in the New Orleans Classic Stakes and an A horse on his Pick 4 tickets.

In addition, Weir is high on a big double-digit long shot on Saturday! Weir says this horse had a "brutal trip" in his last race and could spice up the Pick 4. Weir is using this double-digit 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 the Fair Grounds for Saturday, all from the racing insider who crushed the exacta in the Tampa Bay Derby two weeks ago for $1,414!
