Roger Federer is bringing aboard Pete Sampras' former coach, Paul Annacone, to work with him at the U.S. Open and beyond. Federer announced the hiring on his website Saturday, then discussed it during a pre-Open news conference. He and Annacone began spending time together a month ago to see whether the pairing would make sense. "We've moved it from a test trial to integrating him into the team now," Federer said, "so that's going ahead." http://sports.espn.go.com/sports/tennis/news/story?id=5506449
