"If you're hitting good shots you're going to make a lot of birdies," Simpson said about his round, which featured five birdies, including one on the first hole. "It was really fun to make those five birdies in a row. It's fun to be competitive again. This tour is really fun. I've had so much fun."
Simpson is winless on the Champions Tour since joining the circuit near the end of 2005, but he has at least a share of the lead after the first round for the third time this season.
