Event: Indianapolis 500, Indianapolis Motor Speedway; Speedway, Ind.
TV: Sunday, noon, ABC.
Then and now: One more to go to 100 – Sunday will mark the 99th running of the so-called Greatest Spectacle in Racing at the legendary 2.5-mile Brickyard. ... Ryan Hunter-Reay is the defending champion, but Helio Castroneves is going to have quite a bit of attention as he looks to become only the fourth driver in history to win the Indy 500 four times. The others are Rick Mears, Al Unser and AJ Foyt. ... Canadian driver James Hinchcliffe, who suffered critical injuries in a crash during practice on Monday, was released from Intensive Care on Wednesday. Hinchcliffe suffered injuries to his pelvic area and upper thigh. Ryan Briscoe will replace Hinchcliffe in the race. It’s uncertain how long Hinchcliffe will miss while recovering, but it would not be out of the question if he misses the remainder of the 2015 IndyCar season (11 races are left). ... Juan Pablo Montoya remains atop the IndyCar points standings. Montoya leads Will Power by five points and Castroneves by 10 points. All three drivers are with Team Penske. ... Scott Dixon won the pole at Indy last weekend, ending a streak of pole positions in the last eight consecutive races (the first five this season and the last three of 2014) by Team Penske.

Johnson is third in the Sprint Cup standings, 48 points behind leader Kevin Harvick and two points behind second-place Martin Truex Jr. Harvick won the fall race at Charlotte last season and was the runner-up in last week’s All-Star show in Charlotte. The No. 41 car driven by Kurt Busch had the fastest five- and 10-consecutive-lap averages on this track in his lone practice last week before the All-Star race.

Heading into the race, Chris Buescher is the new points leader, having taken the top spot by virtue of winning at Iowa Speedway this past Sunday.
