Congratulations to HK author Paul Annacone, who was recently hired on a trial basis by Sloane Stephens, the second-ranked American female tennis player. Paul, host of the Paul Annacone Tactical Tennis DVD series, had been Roger Federer’s coach, but last month he split with Federer after 3½ years. He has been working for a few hours every day with Stephens in Los Angeles, where they both live, according to Tennis.com, which first reported the news. Paul also previously coached Pete Sampras and Tim Henman.
