Jimmie Johnson soared to the top of the NASCAR Sprint Cup Series leaderboard Friday at Indianapolis Motor Speedway in an opening practice that featured the return of Jeff Gordon to competition.
Johnson pushed the Hendrick Motorsports No. 48 Chevrolet to a best lap of 184.185 mph around the 2.5-mile track. He'll seek his fifth Indianapolis win in Sunday's Crown Royal Presents The Combat Wounded Coalition 400 at the Brickyard (3 p.m. ET, NBCSN, IMS, SiriusXM NASCAR Radio).
Former Indy pole winner Denny Hamlin was second-fastest in the Joe Gibbs Racing No. 11 Toyota at 182.563 mph, a sizable .434 seconds off Johnson's pace. Casey Mears (180.346 mph), Kevin Harvick (179.845 mph) and Ryan Newman (179.784 mph) completed the top five in the 85-minute opening session.
Gordon clocked the ninth-fastest speed, landing a 179.376 mph lap in the Hendrick Motorsports No. 88 Chevrolet. He's scheduled to make his first Sprint Cup start of the season Sunday as a replacement for Dale Earnhardt Jr. as he recovers from concussion-like symptoms.
Tony Stewart , scheduled to make his final Brickyard start in what's to be his last full-time season, was eighth-fastest at 179.655 mph in the Stewart-Haas Racing No. 14 Chevrolet. The native Hoosier will be vying for his third Brickyard victory in Sunday's 400-miler.
Defending Sprint Cup champion Kyle Busch, also the defending race winner, was 12th-fastest but recovered from a spin at the one-hour mark of the session. Busch's Joe Gibbs Racing No. 18 Toyota made a prolonged slide out of Turn 2 after making contact with the Go FAS Racing No. 32 Ford of Patrick Carpentier.
Carpentier, 44, walked over to Busch's garage stall later in the session to issue an apology for crowding his pass attempt. Carpentier was 39th-fastest of the 41 drivers entered during first practice.
Final Sprint Cup practice is scheduled for tonight from 4-5:25 p.m. ET. Coors Light Pole Qualifying is set for Saturday at 1:45 p.m. ET. Both sessions will be broadcast on NBCSN.
