INDIANAPOLIS (AP) — The speeds have been insane — 234 mph for Scott Dixon in a record-breaking run for the pole — and Jimmie Johnson and Romain Grosjean are both part of the fastest field in the history of the Indianapolis 500. Some 20 drivers, maybe more, are legitimate contenders to win Sunday in front of a crowd expected to swell past 300,000. Roger Penske can finally fully open the gates at Indianapolis Motor Speedway for the first time since he purchased the iconic venue just weeks before the start of the pandemic.
