Horse racing continues to take place daily during the coronavirus pandemic, and on Thursday the Mike Maker-trained Admiral Lynch will try to get back into the winner's circle when he leaves the starting gate at Gulfstream Park in Hallandale Beach, Fla. A 4-year-old son of 2010 Kentucky Derby winner Super Saver, Admiral Lynch has three wins, four seconds and four thirds in 14 career starts. He is coming off a runner-up finish in the World of Trouble Stakes at Gulfstream Park on Feb. 22. He has been installed as the 3-1 morning-line favorite in Race 9.

The race is the third leg of the late Pick 4, which requires a bettor to pick the winner of four consecutive races. The four-race sequence begins with Race 7 at 3:49 p.m. ET and ends with Race 10. Racing insider Bob Weir has handicapped each of the races in the Pick 4, and with the sequence featuring competitive fields, you'll want to see his horse racing predictions and best bets before constructing any late Pick 4 tickets at Gulfstream Park for Thursday, May 21.

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. He cashed the Pick 4 again at the same track on April 30, May 2 and last Friday.

Now, Weir has handicapped the late Pick 4 at Gulfstream Park for Thursday, May 21, made his picks and constructed his best bets. You can head here to see them.

Top Gulfstream Park Pick 4 predictions for May 21

Weir is high on Tide Storm, an 8-1 long shot in Race 8, the second leg of the Pick 4. This 4-year-old daughter of Stormy Atlantic has one win and one second in six career starts. She is coming off a fifth-place finish on April 25.

But that race was at five furlongs, and Thursday's race will be at one mile. "She may take to the route distance after primarily running in turf sprints," Weir tells SportsLine. 

Weir also is high on Wentz, a 5-1 shot in Race 9. This 5-year-old son of Super Saver has four wins, one second and two thirds in 11 career starts. He is coming off a fifth-place finish on March 7.

Trained by John Servis, Wentz has the early speed to be dangerous. "Wentz could be the speed of the speed, breaking from the rail with jockey Luis Saez," Weir added. "He has only one way to go and has a chance to wire this field."
