World class horse racing takes place at Gulfstream Park outside Miami, and on Sunday the late Pick 4 begins with Race 8 at 3:34 p.m. ET and ends with Race 11. Before you make any picks, you NEED to know how Saratoga Springs-based racing insider and Beyer Speed Figure maker Bob Weir has handicapped the sequence.

A member of the Beyer Speed Figure-making team, 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.

In April of this year, he hit a Pick 4 at Gulfstream Park for $641, the exacta in the Florida Derby, a Pick 5 at Keeneland and the exacta in the Lexington Stakes. He smashed the trifecta in the Belmont Stakes for $532.96, and later in June he crushed the Pick 4 at Belmont for $555. Those are just some of his scores this year.

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

We can tell you that Weir is high on Twilight Gleaming, the 9-5 favorite in Race 10, the third leg of the Pick 4. "Twilight Gleaming looks like the fastest and classiest horse in this turf sprint," Weir told SportsLine. "I'm expecting her to come out running and never look back." Twilight Gleaming is Weir's top pick in Race 10 and the only horse from the race on his Pick 4 tickets.

In addition, Weir's top pick in one of the races on Sunday is a double-digit longshot. Weir says this longshot is a "guessing game" who 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 longshot can win? And how has Weir constructed his Pick 4 tickets? ... Join SportsLine now to get Pick 4 selections at Gulfstream Park for Sunday, all from the racing insider who has produced multiple five-figure days at the track!
