William Byron will try for his NASCAR Cup Series-leading third win of the season when he takes part in the 2023 NOCO 400 on Sunday at Martinsville Speedway. The 2018 Rookie of the Year began the season with a pair of disappointing performances, but rebounded with back-to-back victories at Las Vegas and Phoenix. Byron has posted six top-10s in 10 Cup Series starts at Martinsville ahead of NASCAR at Martinsville 2023.

Byron and Chase Elliott, who returns to action after missing six events with a broken leg, are +650 co-favorites in the latest 2023 NASCAR at Martinsville odds from Caesars Sportsbook. Three-time race winner Denny Hamlin, Christopher Bell, Kyle Larson and two-time victor Martin Truex Jr. round out the top 2023 NOCO 400 contenders at +700. The NOCO 400 2023 start time is 3 p.m. ET. You'll want to check out the NASCAR at Martinsville predictions from Micah Roberts, the legendary Vegas bookmaker who pioneered wagering on racing, before locking in any 2023 NOCO 400 picks. 

Roberts was the first to offer expanded NASCAR betting and now hands out NASCAR winners to his followers on SportsLine. Roberts is the nation's premier NASCAR betting expert, and his top pick, Tyler Reddick, won the EchoPark Automotive Grand Prix two weeks ago at +1000 odds.

He also correctly predicted Elliott to win the YellaWood 500 at +1200 last October and the Jockey Made in America 250 in 2021, nailed the 2021 Coca-Cola 600 winner by hitting Larson's victory at +550 odds and was on point by targeting Elliott as the winner of the EchoPark Texas Grand Prix at +160 odds the previous week. Anyone who has followed his picks has cashed ticket after ticket.

Now, Roberts has analyzed the field and odds for Sunday's NASCAR at Martinsville 2023 race. He's sharing his winner and projected 2023 NOCO 400 leaderboard right here.

2023 NASCAR at Martinsville expert predictions 

One shocker: Roberts is fading Kyle Larson, even though he is one of the favorites at 7-1. In fact, Roberts says Larson, who was runner-up at Martinsville last fall and finished fifth in this race two years ago, doesn't even crack the top 15.

"The problem for Larson here is that it's too crowded on the track," Roberts told SportsLine. "He doesn't bump and bang well. It's one of his only weaknesses." See who else to fade here.

Another curveball: Roberts is high on Austin Cindric, even though he's a 75-1 long shot in the latest 2023 NOCO 400 odds. The 24-year-old from Ohio has yet to register a top-10 finish at Martinsville in the Cup Series, but has fared well there on NASCAR's other circuits. Cindric was 10th, sixth and runner-up in three Xfinity Series starts at the track and posted one top-10 in three Truck Series races.

"Cindric was 11th in the spring race at Martinsville last year, finishing in the top 10 in both stages, and 26th in the fall, not too bad for a rookie," Roberts told SportsLine. "His road-course skills should help him here." See who else to back here.
