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 26 NASCAR races in 2019 are already up $1,000! In fact, those who put down $50 on Roberts' top-four leaderboard picks are up $1,900 this year, buoyed by Alex Bowman's 30-1 win at Chicago. He also cashed big with Denny Hamlin winning at Pocono at 10-1.

Roberts got 2019 off to a blazing start picking Jimmie Johnson as a hefty 25-1 long shot at the Advance Auto Parts Clash. At the TicketGuardian 500, Roberts nailed Kyle Busch at 4-1 over the favored Kevin Harvick, and at Dover he won with Martin Truex Jr. at 8-1.

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. In fact, those who wagered $100 on each of his picks last year made $1,750 in profit. Anyone following his picks is up BIG year after year. 

Now, Roberts has analyzed the field for Saturday's Bristol night race. The green flag drops at 7:30 p.m. ET.

We can tell you Roberts is high on Ryan Blaney, an 18-1 shot who won a 2014 Xfinity Series race at Bristol and a 2015 Truck series race there as well. "His next step is winning at Bristol in the Cup Series, and he's been really close lately in his last three races since joining Team Penske last season," Roberts said. "He's been at his best with this week's race package, finishing in the top-five in six of the eight races using it."

But Roberts is eyeing an even bigger long shot that he says can win. This underrated driver already has won multiple times at Bristol and had plenty of success at this iconic track. Anyone who backs this driver could hit it BIG.
