Federer hires new coach

New York - Roger Federer is bringing aboard Paul Annacone as his coach for the US Open and "going forward."

Federer wrote on his website on Saturday that "Paul and I have had a good trial period."

Annacone, an American, is the former coach of Pete Sampras, Marat Safin and Tim Henman. He has been the head coach of men's tennis for Britain's Lawn Tennis Association, and Federer says Annacone will work with him "more and more as his responsibilities with LTA wind down."

In the past, Federer has worked with coaches Darren Cahill, Jose Higueras and Tony Roche, but has also gone without a coach for extended periods.

The US Open starts on Monday.
