Justin Rose asked himself some tough, honest questions last week after he blew a three-shot lead in the final round. He hopes to find the right answers in the AT&T National. With some big par saves in the middle of his round and one last birdie toward the end, Rose shot a 3-under 67 on Saturday to build a four-shot lead over Carl Pettersson (65) and Charlie Wi (70) going into the final round at tough Aronimink Golf Club. http://sports.espn.go.com/golf/news/story?id=5352776
