Horse racing continues to take place daily during the coronavirus pandemic, and on Sunday the Kathy Ritvo-trained Frosted Grace will try to get back into the winner's circle when he leaves the starting gate in an optional claiming race at Gulfstream Park in Hallandale Beach, Fla. A 4-year-old son of Mark Valeski, Frosted Grace has two wins, three seconds and four thirds in 13 career starts. He is coming off a second-place finish at Gulfstream Park on March 26, his fourth straight start finishing either second or third. On Sunday Frosted Grace has been installed as the 7-5 morning-line favorite in Race 9, a six-furlong sprint that drew six entrants. 

The race is the fourth leg of the late Pick 5, which requires a bettor to pick the winner in five consecutive races. The late Pick 5 begins with Race 6 at 3:43 p.m. ET and ends with Race 10. Racing insider Bob Weir has handicapped each of the races in the Pick 5, and with the sequence featuring competitive fields, you'll want to see his horse racing best bets before making any late Pick 5 selections at Gulfstream Park for Sunday, May 10.

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 on a $144 ticket. The following year, he nailed a $31,000 Pick 6 at Gulfstream Park on a $36 investment. In 2016 and 2017, Weir qualified for the prestigious National Horseplayers Championship in Las Vegas.

And this year, his first for SportsLine, Weir has been on fire on his horse racing picks. In January he crushed the Pegasus World Cup, giving out an $8 exacta and a $1 trifecta, winning $757.60. In February's Sam F. Davis Stakes, he gave out the $.50 superfecta, which paid $150.75. In March Weir correctly pegged Wells Bayou to win the Louisiana Derby.

He nailed the late Pick 4 at Gulfstream Park on both April 9 and April 10, hitting for $827.65 and $394.65, respectively. On April 30 he tagged the early Pick 4 at Gulfstream for $154, and on May 2 he scooped up the middle Pick 4 at Gulfstream Park for $477.90.

Now, Weir has handicapped the late Pick 5 at Gulfstream Park on Sunday, made his picks and constructed his best bets. You can head here to see them.

Top Gulfstream Park Pick 5 predictions for May 10

Weir is high on Carolyn's Smile, a 5-2 shot in Race 6, the opening leg of the Pick 5. This 3-year-old daughter of Khozan has two seconds and one third in five career starts. She is coming off a second-place finish on April 10.

Carolyn's Smile earned a career-best 67 Beyer Speed Figure in that race and continues to improve with each start. "She could be the controlling speed and returns to facing state breds," Weir tells SportsLine. 

Weir also is high on Who's in Charge, a 6-1 long shot in Race 10. A $150,000 purchase two years ago, Who's in Charge has two wins in three career starts. He enters Sunday's race off a three-plus month layoff.

But in his last race, Jan. 20 at Aqueduct, Who's in Charge won in hand by 3.5 lengths. "Son of Take Charge Indy might be outclassed, but his last race was impressive," Weir added.
