Wilson BLX Six One Tour 90 - L4 (4 1/2") This ultra rare racquet model was endorsed by Roger Federer from 2010 through 2011, including his win at the 2010 Australian Open. It is absolutely brand new with the factory card stock still attached in the hoop. It has an 4 1/2" (L4) grip size and original factory Wilson leather grip. I have included photos of Roger and photos of the actual racquet you will receive. Please see photos for details of the racquet as evidence of its condition before bidding. A signature will be required upon delivery.
