Saturday is the biggest day of the year at Pimlico Race Course in Baltimore, Md., Preakness Stakes day, the late Pick 4 begins with the Sir Barton Stakes at 4:10 p.m. ET and ends with the Preakness. 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 since 2017, 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 and an $18,000 Pick 5 at Tampa Bay Downs in early April.

In April of last 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 a Pick 4 at Belmont for $555. Those were just some of his scores for SportsLine from 2023.

And on Friday, Weir hit the winner and the exacta in the Black-Eyed Susan Stakes at Pimlico.
