It turns out Phil Mickelson might be getting better with age.

Mickelson became the oldest golfer to win a major championship, shooting a final-round 1-over-par 73 to capture the PGA Championship by two shots at The Ocean Course in Kiawah Island, South Carolina, on Sunday.

"This is just an incredible feeling because I just believed that it was possible but yet everything was saying it wasn't," Mickelson said. "I hope that others find that inspiration. It might take a little extra work, a little bit harder effort to maintain physically or maintain the skills, but gosh, is it worth it in the end."
