Belmont Park's Empire 6 on Sunday is a mandatory-payout, providing the potential for a HUGE score. The six-race sequence begins with Race 4 at 2:09 p.m. ET and ends with Race 9. Before you make any picks, you NEED to see the picks from racing insider and accomplished horseplayer Bob Weir.

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. 

And this year, his first for SportsLine, Weir has been on fire. In January he crushed the Pegasus World Cup, giving out an $8 exacta and a $1 trifecta, winning $757.60. He nailed the late Pick 4 at Gulfstream Park on both April 9 and April 10, hitting for $827.65 and $394.65. On June 13 Weir hit a $2 superfecta in the Ogden Phipps Stakes that paid a whopping $1,039. And 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. Those are just some of his hits this year.

Anyone who has followed Weir this year is WAY UP.

Now, Weir has handicapped the Empire 6 at Belmont Park for Sunday, made his picks and constructed his tickets.

We can tell you that Weir is high on Onthewaytonevrland, a 7-2 shot in Race 5, the second leg of the Empire 6. "A 4-year-old for trainer Wesley Ward, Onthewaytonevrland will be making his first start in claimers," Weir tells SportsLine. Onthewaytonevrland is Weir's top pick in the race and a single A horse on his Empire 6 tickets.

In addition, Weir's top pick in one of the races is a longshot! Weir says this horse "endured a terrible trip" in its last start and could light up the toteboard and spice up the Empire 6. You NEED to see Weir's analysis before making any Empire 6 picks!
