INDIANAPOLIS — Brad Keselowski took the lead when Elliott Sadler was penalized for jumping a late restart, then held on to win Saturday in a controversial finish to the first NASCAR Nationwide Series race at Indianapolis Motor Speedway. Sadler passed Keselowski on a restart with 18 laps to go, but officials ruled that Sadler went too early and black-flagged him. Sadler stayed on the track for several laps, apparently hoping officials would reconsider the penalty, before finally coming in with 12 laps to go and giving up the lead to Keselowski. Keselowski went unchallenged to the finish on the historic 2.5-mile (4-km) oval. Sam Hornish Jr. was second, followed by Ty Dillon, Denny Hamlin and Austin Dillon. Sadler finished 15th. Danica Patrick's day ended early after she collided with Reed Sorenson on lap 39. Kyle Busch dominated the first half of the race, but got shuffled back in the field during a round of pit stops on lap 63 and Hornish took the lead. Keselowski then passed Hornish for the lead with 29 laps to go, and a caution came out shortly afterward. Busch was fourth on the subsequent restart but spun out right after the race went green. He managed to avoid major damage but lost his shot at the win. Sadler then shot past Keselowski on a restart with 18 laps to go — but Sadler was black flagged for jumping the start. It was the first-ever Nationwide race at the historic oval, part of an effort by officials to drum up interest and boost sagging attendance at the Brickyard 400. But the addition of Nationwide to the weekend schedule didn't prove to be an immediate hit with fans, as the grandstands were largely empty Saturday. And any fans who came to see Patrick race didn't get to see much of her. Patrick appeared to tap Sorenson's back bumper going into Turn 1, causing the back end of Sorenson's car to slide sideways. Sorenson nearly saved it, but his left-front wheel got into the infield grass, causing him to spin out. Patrick then hit Sorenson's car, causing heavy damage. — AP
