Nine previous winners will attempt to recapture the glory when they compete in the 2023 Indianapolis 500 on Sunday at Indianapolis Motor Speedway. Marcus Ericsson is aiming to become the first driver to post back-to-back victories since Helio Castroneves, who accomplished the feat in 2001 and 2002. The 47-year-old Brazilian took the checkered flag for the fourth time in 2021, tying legends A.J. Foyt, Al Unser and Rick Mears for most Indy 500 wins.

Ericsson is +1100 and Castroneves is +5500 in the latest 2023 Indianapolis 500 odds from Caesars Sportsbook, while Pato O'Ward is the +500 favorite. The green flag drops at 12:45 p.m. ET.

Before making any 2023 Indy 500 picks, you NEED to see what SportsLine's Micah Roberts has to say. A former Vegas bookmaker, Roberts was the first to offer expanded auto racing betting and now hands out winners to his followers on SportsLine.

In 2016, rookie Alexander Rossi shocked the world, winning the Indy 500 as a +8000 long shot. Roberts, the nation's premier auto racing betting expert, was all over Rossi.

The following year, sportsbooks listed Takuma Sato as a +2500 long shot, but Roberts liked his speed during practice runs and listed him in the top 10 of his projected leaderboard. The result: Sato stunned the IndyCar world with his first win since 2013, and anybody who backed him saw a massive return.

Roberts also had 2018 winner Will Power, who was listed at +1000, in his top 10 and correctly predicted Simon Pagenaud to win the Indianapolis 500 a year later. Spot-on picks are the norm from Roberts, who is locked in on this year's running of the Indianapolis 500 and just revealed his projected leaderboard.

We can tell you he's fading O'Ward, even though he is the favorite at +500. In fact, Roberts says O'Ward barely even cracks the top 10!

Roberts also has identified a long-shot driver with a strong chance of taking the checkered flag. Vegas isn't particularly high on this driver, so you could cash in HUGE on Sunday. You ABSOLUTELY need to see who it is before entering your picks!
