It took no time at all for drivers to reach 230 miles per hour as IndyCar allowed qualifying boost for the first time in an IMS practice session. Two crashes 11 minutes apart interrupted the otherwise clean running time.

Just past the halfway mark of the two and one half hour session Kyle Larson made contact with the wall in turn 1, then e slid to the inside of track. The damage looked slight, and Larson was cleared by the medical staff.

Practice resumed, but only for a moment before Takuma Sato made hard contact in turn 1, slid into turn 2 and hit the wall again. Sato had turned the second fastest lap of the day and was atop the no tow chart at the time of his accident. The car looks like a total loss.

Sato mwas treaqted and released from the infield care center.

Scott McLaughlin had the fastest single lap at 232.686. 12 drivers topped 230 mph.

Kyle Kirkwood had the best four lap average and the second best no tow speed behind Sato.

If this were Fast Friday, the pattern heading into qualifying would look familiar- Penske Chevys vs. the Honda teams. Andretti and Ganassi cars look to be near equal in speed. The pole could be one heck of a battle.

The top ten single lap speeds:
