Phil Mickelson showed off his arm for, apparently, the last time at the Phoenix Open on Saturday afternoon.
Lefty threw about 10 footballs right-handed into the crowd and regretted it after his round, according to Brian Wacker of PGATour.com.
"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."
