As a Vegas bookmaker, Micah Roberts was the first to offer expanded NASCAR betting. Now he hands out NASCAR winners to his followers, and he's already up huge this season.

Those who have wagered $100 on Roberts' winning pick for each of the NASCAR races in 2019 are up $1,500. In fact, those who put down $50 on Roberts' top-four leaderboard picks are up $2,800 on the year, buoyed by Alex Bowman's big win at Chicago at 30-1 odds -- Roberts had the huge underdog in his top four. One of his top four picks has won six of the last eight races, including Denny Hamlin (12-1) at Bristol, Erik Jones (16-1) at Darlington and Chase Elliott (8-1) at Charlotte Motor Speedway's Roval road course.

Roberts got 2019 off to a blazing start, calling 25-1 long shot Jimmie Johnson's win in the Advance Auto Parts Clash. At the TicketGuardian 500, Roberts nailed Kyle Busch at 4-1 over the heavily favored Kevin Harvick, and at Dover he won with Martin Truex Jr. at 8-1. Truex won despite starting at the back of the field.

Roberts' top 20 leaderboard has been on top of it, too. At the TicketGuardian 500, he nailed an eye-popping eight of the top 10. At the Auto Club 400, he got nine of the top 10 correct.

Roberts entered the 2019 NASCAR season after finishing big-time in the black in 2018. Those who wagered $100 on each of his picks last year saw $1,750 in profit. Anyone who's following his picks is up HUGE year after year. 

Now Roberts has analyzed the field for Sunday's 1000Bulbs.com 500. The green flag drops at 2 p.m. ET.

We can tell you Roberts is fading Kyle Busch, the co-fifth choice in the 1000Bulbs.com 500 odds, at 14-1. Roberts has Busch ranked 15th on his leaderboard.

"He's a good racer at Talladega and Daytona, but I don't think he likes this particular track during the playoffs as he chases his second Cup title," Roberts told SportsLine. "His lone Talladega win came in 2008. He was 10th in the April race."

However, Roberts is extremely high on a massive longshot who has been outstanding with this race package. "I don't know the last time I was so excited to bet a longshot as I am this week," Roberts told SportsLine. Anyone who backs this driver could hit it BIG.

So who wins the 1000Bulbs.com 500? And which massive long shot stuns NASCAR? ... Join SportsLine right now to see the full projected leaderboard for NASCAR at Talladega, all from the nation's premier NASCAR betting expert who's up HUGE year after year!
