Indianapolis • Team Penske's Will Power pushed Chevrolet to the top of the Indianapolis 500's practice speed chart.

His fast lap of 232.672 mph was the best Friday and the best all week. Another Chevy driver, Josef Newgarden of Ed Carpenter Racing, finished second at 232.344.

Qualifying will be held Saturday and Sunday on the historic 2.5-mile oval.

• Rain washed out all track activity Friday at Charlotte Motor Speedway, which will now try to cram its All-Star weekend into one day. The showers forced NASCAR to call off the scheduled Sprint Showdown, a race that will send five drivers not already qualified for the All-Star race, into the main event. The Truck Series race also was postponed. Both events were rescheduled for early Saturday, with the $1 million All-Star Race still scheduled to go off in the evening. NASCAR set the showdown field by points.
