Associated Press Brad Keselowski had a couple of impressive performances at New Hampshire. It’s the victory celebration that again gave him fits. Keselowski topped all the fields Saturday at New Hampshire Motor Speedway, including a dominant run in his Nationwide Series victory. Keselowski also led the speed charts during both Sprint Cup practices. Throw in the pole for the Nationwide race and that made the Team Penske driver a neat 4 for 4. Simply perfect. “Well a hell of a Saturday,” Keselowski said. His only hiccup came when he dropped the American flag out of his No. 22 Ford. The flag rested on the track before it was retrieved by an official to let the victory celebration continue. “It was really windy and my hand’s been sore,” he said. “I took my hand off the flag for the second and the wind ripped it out. It wasn’t one of my prouder moments.” Keselowski needed four stitches to close a wound he received during his Victory Lane celebration in the Sprint Cup race at Kentucky. He tried to open the bottle of champagne by hitting it against a podium, and the bottle broke and cut his hand. Keselowski led 153 of the 200 laps in his second Nationwide win of the season. He also won at Phoenix.
