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 Miles Ahead, the 9-5 favorite in Race 8, the second leg of the Pick 4. "He loves Gulfstream Park, the distance and, apparently, jockey Paco Lopez," Weir tells SportsLine. Miles Ahead is Weir's top pick in Race 8 and a single A horse on his Pick 4 tickets.

In addition, Weir is high on a double-digit long shot on Sunday! Weir says this horse "ships in" and "could surprise" and 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.
