Friday at Churchill Downs is dedicated to the fillies, and the marquee race on the card is the 2021 Kentucky Oaks. Thirteen fillies will leave the starting gate after a 14th, Ava's Grace, scratched from the race. The Kentucky Oaks 2021 features an evenly-matched field with the top three favorites tightly grouped. The Todd Pletcher-trained Malathaat is the 5-2 morning line favorite in the 2021 Kentucky Oaks odds.

Two fillies, Travel Column and Search Results, are right behind in the 2021 Kentucky Oaks field at 3-1. Clairiere is 5-1 and nine other 2021 Kentucky Oaks horses are 15-1 or higher on the morning line. The Kentucky Oaks 2021 post time is set for 5:51 p.m. ET. With an accomplished field set to enter the starting gate on Friday, you'll want to see what racing insider Bob Weir has to say before making any Kentucky Oaks picks.

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.

Last year, his first for SportsLine, Weir was on fire. In June, Weir hit a $2 superfecta in the Ogden Phipps Stakes that paid a whopping $1,039. He crushed the exacta and trifecta in the Forego Stakes in August for $1,134.50. 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.

This year, he hit the exacta in the Sam F. Davis Stakes and Tampa Bay Derby and the trifecta in the Risen Star Stakes and Blue Grass Stakes. Those are just some of his scores in 2021.

Now, he has handicapped the 2021 Kentucky Oaks field, made his picks and constructed his bets. You can only see them here.

Top 2021 Kentucky Oaks expert picks

One shocker: Weir is almost completely fading Search Results, even though she is the second-biggest favorite at 3-1. Trained by Chad Brown, Search Results is looking to go a perfect four-for-four in her career and is coming off a victory in the Gazelle Stakes on April 3.

However, she was disadvantaged by drawing post No. 12 in the Kentucky Oaks 2021. "Breaking from the outside, she might be used hard early to get in position entering the turn or forced to drop into a new position for her," Weir told SportsLine. "Her results can't be ignored, but I will play against her on top."

Another surprise: Weir is high on Millefeuille, even though she is a 20-1 long shot. Named after a French pastry, Millefeuille has one win and three seconds in five career starts. She is coming off a runner-up finish in the Gulfstream Park Oaks on March 27.

Since that race, she has trained well, firing three straight bullet workouts. The sharp morning exercises suggest she is ready to run well on Friday. "She might continue to move forward in her third start [of 2021]," Weir told SportsLine.
