World class thoroughbred racing takes place at Belmont Park in Elmont, N.Y., and on Sunday the late Pick 4 begins with Race 7 at 4:10 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. (Check out all of SportsLine's horse racing coverage.)

Saratoga Springs-based racing insider and Beyer Speed Figure maker Bob Weir has studied the races and formulated a Pick 4 ticket 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. This year, he has been 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 and Blue Grass Stakes and the superfecta in the Belmont Stakes. Those are just some of his scores in 2021.

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

We can tell you that Weir is high on Tallis, a 9-2 shot in Race 10, the final leg of the Pick 4. "His dam was a stakes winner on turf, and his half-brother has raced competitively on turf this year as 2-year-old," Weir says. "He could take to the surface and gets a pretty suspect field for his belated turf debut."

In addition, Weir is high on a double-digit long shot on Sunday! Weir says this horse "could be a handful late" 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 Belmont Park for Sunday, all from the racing insider who has been on fire!
