The Christophe Clement-trained Gufo makes his first start as a 4-year-old when he leaves the starting gate in the 2021 Man o' War Stakes on Saturday at Belmont Park in Elmont, N.Y. This son of Declaration of War has never finished off the board in eight career starts, with five wins, one second and two thirds. He last raced on Thanksgiving weekend, finishing third in the Hollywood Derby. For Saturday Gufo is listed at 2-1 in the 2021 Man o' War odds. 

The Chad Brown-trained Sovereign is the 8-5 favorite in the 2021 Man o' War field. Ziyad and Field Pass are both listed at 6-1. Post time is set for 5:44 p.m. ET. With a well-accomplished field set to enter the starting gate on Saturday, you'll want to see what racing insider Bob Weir has to say before making any 2021 Man o' War 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. On June 13, 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 has 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, with the Tampa Bay Derby score returning $1,414. Those are just some of his biggest hits for SportsLine.

Now, Weir has handicapped the 2021 Man o' War field, made his picks and constructed his bets. You can only see them here.

Top 2021 Man o' War Stakes predictions

After studying the past performances of every horse in the race, Weir is bullish on the chances of Field Pass, who is at 6-1 in the odds, behind only Sovereign and Gufo. A son of 1999 Belmont Stakes winner Lemon Drop Kid, Field Pass is looking for his seventh career victory. In his last start he returned from a three-month layoff to finish fourth in the Maker's Mark Mile at Keeneland.

On Saturday Field Pass stretches out in distance from one mile to 1⅜ miles. "Trainer Mike Maker is one of the best at getting horses to stretch out," Weir tells SportsLine. Weir will use Field Pass in his exactas, trifectas and superfectas.
