IndyCar Watkins Glen: Scott Dixon leads crash-interrupted practice

Just 10 minutes into the session, Daly lost control of his Dale Coyne Racing entry over the kerb exiting Turn 6, spinning across the track and into the barriers.

Water contained in the kerbs from earlier rain had contributed to Daly's off, and meant for a lengthy red flag period as attempts were made to dry the kerbs around the circuit.

The session eventually restarted over 20 minutes later with less than 10 minutes remaining, but the scheduled running was then extended by a further 10 minutes.

With the times set prior to the red flag proving unrepresentative, Chip Ganassi Racing driver Dixon went to the top of the times and finished up with a best lap of 1m23.892s.

That was 0.363 seconds quicker than closest rival Sebastien Bourdais of KVSH Racing.

Will Power was the lead Penske driver in third, over eight tenths down on Dixon.

Close behind Power were Tony Kanaan, the top Honda-powered runner Graham Rahal, Juan Pablo Montoya and Josef Newgarden.

Championship leader Simon Pagenaud, Helio Castroneves and Indianapolis 500 winner Alexander Rossi completed the top 10.
