A late-race speeding penalty dashed Scott Dixon’s quest for a second Indianapolis 500 crown.

The 42-year-old New Zealander controlled the race for a race-high 95 laps and surpassed Al Unser’s record lap leader mark of 644 on Lap 133. He was engaged in a tight battle for the win with Arrow McLaren SP’s Pato O’Ward in the race’s final quarter.

Dixon darted to the pits on Lap 175 and locked up the wheels of his No. 9 PNC Bank Honda heading onto pit lane. The lockup resulted in the 51-time Indy car race winner getting a drive-through penalty for speeding on pit road.

Dixon ended up 21st at the flag while teammate Marcus Ericsson claimed the victory.

“It’s just heartbreaking, to be honest,” Dixon told NBC. “I don’t know. It must have been very close. I kind of came into the pit and had to lock the rears. Kind of locked all four and I knew it was going to be close. I think it was a mile an hour over or something. Just frustrating.

“The car was really good all day. We had really good speed. I think the team did an amazing job on strategy. I just messed up.”
