History will be made Sunday as Chicago hosts the 2023 Grant Park 220, the first street race contested in the NASCAR Cup Series. The race will consist of 100 laps and take place on a 2.2-mile course that features 12 turns. Martin Truex Jr. looks to increase his points lead and join William Byron and Kyle Busch as the only drivers with three victories this season.

Chase Elliott is the +500 favorite and Tyler Reddick is listed at +650 in the latest 2023 Grant Park 220 odds from Caesars Sportsbook. Truex and Kyle Larson are +700 while Ross Chastain and A.J. Allmendinger are +1000 in the 2023 NASCAR at Chicago odds. The green flag drops at 5:05 p.m. ET.

Before making any 2023 Grant Park 220 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, Chastain, won the Ally 400 last week at +1000. He also predicted 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 Reddick's victory at +1000.

In addition, the expert 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 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 Grant Park 220. We can tell you he's fading Elliott, even though he is the favorite at +500. In fact, Roberts says Elliott doesn't even crack the top five!

Instead, Roberts is high on a longshot who has "finished in the top 10 in each of his last seven road starts." 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.
