Watch Now: Triple Crown Chase: Easier Or Tougher With New Schedule (2:22)

Horse racing continues to take place daily during the coronavirus pandemic, and on Sunday the Graham Motion-trained Mercilla will try to get back into the winner's circle when she leaves the starting gate in an optional claiming race at Churchill Downs in Louisville, Ky. A 4-year-old daughter of Arch, Mercilla has two wins and one second in six career starts. She last raced on Nov. 30, finishing sixth in a Grade 3 stakes at Aqueduct. On Sunday she has been installed as the 4-1 morning-line favorite among those drawn into the main field for Race 9, a nine-furlong turf race that drew 12 entrants, four also-eligibles and one main-track-only runner. 

The race is the third leg of the late Pick 4, which requires a bettor to pick the winner in four consecutive races. The Pick 4 begins with Race 7 at 4:08 p.m. ET. National handicapping champion Jonathon Kinchen has evaluated each of the four races in the late Pick 4, and with the sequence featuring large and competitive fields, you'll want to see his horse racing predictions before making any late Pick 4 selections at Churchill Downs for Sunday, May 24.

Kinchen is one of the nation's most successful and recognizable horseplayers. An analyst for Fox Sports' "Saturday at the Races," Kinchen won the National Horseplayers Championship Tour in 2015, a demanding, yearlong series of handicapping events across the country. That same year, he became the only player in history to have both of his entries qualify for the final table of the National Horseplayers Championship.

In addition, Kinchen has scored huge on some of racing's biggest days. At the 2015 Kentucky Derby, he cashed for $150,000 after nailing a Pick 6 and a $300 Pick 3 that paid $50,000. He also hit a Pick 4 for $84,000 on Belmont Stakes day in 2010, one of several five-figure days he has had at the track.

He's currently riding a hot streak on his horse racing picks for SportsLine. In the Fountain of Youth Stakes in February, Kinchen nailed an $80 win bet on Ete Indien that paid a healthy $344. In the Beholder Mile in March, he gave out a $50 exacta that paid $550. In the Apple Blossom Handicap, he nailed a $25 win bet on Ce Ce, which paid $245. He also hit the Pick 4 at tracks around the country a whopping five times in April. Anyone who has followed him is up big.

Now, Kinchen has handicapped the late Pick 4 at Churchill Downs for Sunday, May 24, made his picks and constructed his tickets. Head to SportsLine to see his best bets

Top Churchill Downs Pick 4 predictions for May 24

Kinchen is high on Charming Lady, a 4-1 shot in Race 8, the second leg of the Pick 4. This 3-year-old daughter of Ghostzapper has one win, two seconds and one third in four career starts. She is coming off a second-place finish on April 26.

In that race, she earned a career-best 79 Beyer Speed Figure. "Charming Lady ran a solid second in an allowance race at Oaklawn Park in her last start, finishing behind Edgeway, who's a talented, stakes-caliber filly," Kinchen tells SportsLine. 

Kinchen also is high on Whispering Beauty, a 5-1 shot in Race 9. This 4-year-old daughter of Arch has two wins, two seconds and one third in six career starts. She is coming off a runner-up finish at Gulfstream Park on April 24.

But that race was on dirt, and Sunday's race will be on turf, her preferred surface. "Her turf races earlier this year were good, and she should get a great trip from the 2 hole," Kinchen added.
