Top thoroughbred racing takes place at Gulfstream Park in Hallandale Beach, Fla., and on Sunday the late Pick 4 begins with Race 7 at 3:37 p.m. ET and ends with Race 10. Before you make any picks, you NEED to know how racing insider and accomplished horseplayer Bob Weir has handicapped the four-race sequence.

A Saratoga Springs-based racing insider and Beyer Speed Figure maker, Weir has studied the sequence and constructed his wagers in his analysis below. A two-time qualifier for the prestigious National Horseplayers Championship in Las Vegas, Weir 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 on fire. He hit the exacta in the Sam F. Davis Stakes, Tampa Bay Derby and Peter Pan Stakes, the trifecta in the Risen Star Stakes, Blue Grass Stakes and Pennsylvania Derby and the superfecta in the Belmont Stakes, with the Tampa Bay score returning $1,414. Those were just some of his scores in 2021.

Now, he has handicapped the late Pick 4 at Gulfstream Park for Sunday, made his picks and constructed his tickets.

We can tell you that Weir is high on Kitten's Mischief, the 7-5 favorite in Race 8, the second leg of the Pick 4. "It's dangerous to put too much faith in a debut win in an off-the-turf affair, but Kitten Mischief might be the exception," Weir tells SportsLine. Kitten's Mischief is Weir's top pick in Race 8 and a single 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 gets "his best opportunity in a long time" 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 Gulfstream Park for Sunday, all from the racing insider who has been on fire!
