Hey everyone. It's been a while since I've updated this chart.
In 2014, we learned that Federer played with a stealth, blacked-out, matte finish, 97 square-inch prototype at the Australian Open, French Open, and Wimbledon. After Wimbledon, Wilson revealed the official retail Pro Staff RF97 Auto, which Federer used at the US Open. 2014 is in the books. Enjoy!
