Eleven three-year-olds will try to take a step towards the 2021 Kentucky Derby when they leave the starting gate in the 2021 Lecomte Stakes on Saturday at Fair Grounds Race Course. The Brad Cox-trained Mandaloun is the 3-1 morning-line favorite. Post time is 6:49 p.m. ET.

Before you make any 2021 Lecomte Stakes 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.

And last year, his first for SportsLine, Weir was on fire. In January he crushed the Pegasus World Cup, giving out an $8 exacta and a $1 trifecta, winning $757.60. On June 13 Weir hit a $2 superfecta in the Ogden Phipps Stakes that paid a whopping $1,039. He nailed the exacta and trifecta in the Forego Stakes in August for $1,134.50. And he hit the late Pick 4 at Belmont Park on June 18, June 19, June 25, July 2 and July 5, with the June 25 score returning a whopping $2,159.50! Those were just some of his hits last year. Anyone who has followed Weir is WAY UP.

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

One shocker: Weir is mostly fading Proxy, even though he's one of the favorites at 6-1! Instead, Weir's top pick is a horse who "should appreciate the stretch" in distance. He's also high a long shot to STUN the field! Weir is including these horses in his wagers, and so should you. You ABSOLUTELY need to see which horses they are before locking in any picks!
