Detroit – A handful of IndyCar drivers took the track at approximately 10 Sunday morning to check track conditions in the rain on the 2.3-mile road course on Belle Isle.
Former series champion Scott Dixon and Ryan Hunter-Reay were among the drivers to test the conditions, along with 2013 Indy 500 winner Tony Kanaan, while the song "Who'll Stop the Rain" by Creedence Clearwater Revival blared in the media room.
The Pirelli World Challenge Race No. 2 set for noon was canceled "due to safety concern and track visibility both for the drivers and course workers."
Kevin Estre beat points leader Olivier Beretta in Race No. 1 of the Pirelli World Challenge Saturday, ending Johnny O'Connell's winning streak in the series on the island in a Cadillac.
Carlos Munoz won the rain-shortened IndyCar Race No. 1 Saturday to earn his first career victory. The scheduled 70-lap race was called after 47 laps due to lightning and heavy rain.
Qualifying for Race No. 2 is set for 11:25 a.m. with the race to get underway at 3:50 p.m.
Indy 500 winner Juan Pablo Montoya holds the points lead with Team Penske teammate Will Power 11 points back at 281, followed by Dixon with 241.
