A field of nine horses will try to take a step towards the Kentucky Derby when the starting gate opens on Saturday in the 2021 Holy Bull Stakes at Gulfstream Park. The Shug McGaughey-trained Greatest Honour is the 5-2 favorite in the 2021 Holy Bull odds. Post time for the 1 1/16-mile race is 4:50 p.m. ET. 

Before you make any 2021 Holy Bull picks, you NEED to see what racing insider Bob Weir has to say.

Based in Saratoga Springs, N.Y., Weir has been handicapping and following horse racing since reading Andy Beyer's landmark handicapping book "Picking Winners" in the late 1980s. Weir is highly invested in the Beyer Speed Figure, a number assigned to every race run by a horse that measures how fast the horse ran. He uses the figure as the backbone of his handicapping. In fact, thanks to his proficiency with speed figures and top-tier handicapping, he landed one of just eight spots on Beyer's figure-making team in 2017, a position he holds to this day.

Weir's methodology has produced multiple five-figure days. In 2014, he hit a $60,000 Pick 6 at Del Mar. The following year, he nailed a $31,000 Pick 6 at Gulfstream Park. In 2016 and 2017, Weir qualified for the prestigious National Horseplayers Championship in Las Vegas! Anyone who has followed Weir is WAY UP.

Now, he has handicapped the 2021 Holy Bull Stakes field, made his picks and constructed his bets. 

One shocker: Weir's top pick is not the favorite, Greatest Honour, who is 5-2 on the morning line. "Greatest Honour may ultimately want more than the 1 1/16 miles," Weir tells SportsLine.

Instead, Weir's top pick is a horse who "could be something special!" He also is high on a double-digit long shot who is "capable of hitting the board." Weir is including these horses in his exactas, trifectas and superfectas, and so should you. You ABSOLUTELY need to see which horses they are before locking in any picks!
