Who has the better backhand, Roger Federer or his dad?

"According to TennisWorldUSA.org, the above video was taken Saturday afternoon at Roger Federer’s practice session just before today’s ATP World Tour semifinal with Stan Wawrinka. Game, set and match definitely goes to Roger’s dad (and he may have the better one-handed backhand, too). More important, looks like a good time was had by all and there were no hard feelings about the head-hunting backhand that Mr. Federer so devilishly sent in the direction of his son."

I'd heard rumours about papa Fed going all Mr. Miyagi on his son. Thanks for the video.

On clay, against Nadal my 5 foot tall 260 pound granny, god rest her soul has a better backhand.

Maybe theyll go dragon ball z style fusion... his dad can take the bh side . Or it goes wrong and his dad gets the fh side
