Martin Truex Jr. will try to continue his strong run at Richmond Raceway when he competes in the 2023 Cook Out 400 on Sunday. The 2017 NASCAR Cup Series champion has posted top-10 finishes in 11 of his last 14 starts at Richmond and reeled off eight in a row before finishing 11th at the track in April. Truex is the +450 favorite in the 2023 Cook Out 400 odds from Caesars Sportsbook. Three-time race winner Denny Hamlin is +550 and Kyle Larson is +600 in the 2023 NASCAR at Richmond odds. The green flag drops at 3 p.m. ET.

Before making any 2023 Cook Out 400 picks, you NEED to see what SportsLine's Micah Roberts has to say. A former Vegas bookmaker, 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, Hamlin, won the HighPoint.com 400 last weekend at +500. He also predicted Truex's victory at +650 in the Crayon 301 the previous week and Ross Chastain's triumph at +1000 in the Ally 400 last month. In addition, Roberts correctly called Larson's win at +650 in the NASCAR All-Star Race in May and nailed the EchoPark Automotive Grand Prix winner in March by hitting Tyler Reddick's victory at +1000.

In addition, the expert correctly predicted Chase 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 and was on point by targeting Elliott as the winner of the EchoPark Texas Grand Prix at +160 the previous week. Anyone who has followed his picks has cashed ticket after ticket.

Now, Roberts has analyzed the field for Sunday's Cook Out 400. We can tell you he's fading Kevin Harvick, even though he is one of the favorites at +700. In fact, Roberts says Harvick barely even cracks the top 10!

Instead, Roberts is high on a MASSIVE longshot who has "had great runs at Richmond in his last two shots at it." This driver is being vastly underestimated by oddsmakers, and anyone who backs him could hit it BIG! You ABSOLUTELY need to see who it is before making any picks.
