Last but by no means least on my series from this week’s ATP World Tour Finals at London’s O2 Arena is the arguably the greatest player of all time, the one and only Roger Federer.

Although losing to Novak Djokovic in last night’s final, he did beat the World #1 three times this year, including a comprehensive victory in pool play at this year’s event. At 34 he shows no signs of slowing up ,in fact quite the opposite and will start the 2016 season in third spot, hoping to add to his record 17 Grand Slam titles.

Former World #1 Jimmy Connors summed up Roger’s status,”In an era of specialists, you either have a clay court specialist, a grass court specialist or a hard court specialist… or you’re Roger Federer.”

That’s enough about the great man, what about his weapon? He plays with a Wilson Prostaff RF97 Autograph, 97 square inch racquet with a 21.5 mm beam, weighing 360g with a 331 swing weight and 16 x 9 string pattern, strung with over grip. When I caught up with him at the O2 before last nights final, the uber-cool and relaxed, designer-stubbled Swiss superstar, the only part of the racquet specs he had with him was his autograph which he signed on this sketch for me.
