It turns out Lefty's not too bad as a righty.

Phil Mickelson showed off his cannon for a right arm over the weekend at the Waste Management Phoenix Open. During the par-3 16th hole, Mickelson took a break from the tournament to toss a few footballs into the crowd. And wait until you see his throws.

The 43-year-old, who has won five major championships, is a natural righty and it shows here. He chucks the footballs into the stands with impressive strength and precision.

The balls were Arizona State footballs and signed by Mickelson. Mickelson played golf at Arizona State and his brother is the school's men's golf coach.

While this looks like a lot of fun, Mickelson says he won't be breaking out the pigskin on the course anytime soon.

"I think it's the last time I'm going to do that, because mentally I was thinking about throwing it a couple holes prior," Mickelson said. "It took me out of my element. I hit the worst shot imaginable on that 16th hole, and then I followed with four other terrible ones. It was just some of the worst shots imaginable.

"I just lost focus, and I think a lot of it was due to the fact that I have never done something like that on the 16th hole. I thought it was going to be fun, and it kind of took away my focus."

Mickelson, the tournament's defending champ, finished the day with a 72 and dropped to 3-under par.
