World class horse racing takes place at Belmont Park outside New York City, and on Sunday the late Pick 4 begins with Race 6 at 3:34 p.m. ET and ends with Race 9. Before you make any picks, you NEED to know how racing insider and accomplished horseplayer Bob Weir has handicapped the sequence.

A member of the Beyer Speed Figure-making team who is based in Saratoga Springs, N.Y., 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.

Last year he was red-hot in the Triple Crown prep races, hitting the superfecta in the Blue Grass Stakes for $1,678 and exactas in the Fountain of Youth Stakes and Tampa Bay Derby. He also hit the 19-1 winner of the Man o' War Stakes, the trifecta in the Pegasus World Cup, the superfecta in the Met Mile and multiple Pick 4s, including May 14's at Belmont for $1,851.

In April of this year, he hit a Pick 4 at Gulfstream Park for $641 and the exacta in the Florida Derby. Seven weeks ago, he nailed the Pick 5 at Keeneland and the exacta in the Lexington Stakes. Those are just some of his scores this year.

For Sunday, Weir has handicapped the late Pick 4 at Belmont Park, made his picks and constructed his tickets.

We can tell you that Weir is high on Liberty Flame, the 9-5 favorite in Race 6, the opening leg of the Pick 4. "She owns the best speed in the race, draws the rail and adds jockey Kendrick Carmouche. That sounds pretty good to me," Weir told SportsLine. Liberty Flame is Weir's top pick in Race 6 and the only horse from the race on his Pick 4 tickets.

In addition, Weir is high on a double-digit longshot on Sunday. Weir says this horse "just might be getting better" 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? ... Join SportsLine now to get Pick 4 selections at Belmont Park for Sunday, all from the racing insider who has produced multiple five-figure days at the track!
