Fabio Fognini,Tommy Robredo, John Isner, Youzhny gain in rankings Fabio Fognini, shown at the 2013 French Open, has reached a career-best 16th in the ATP rankings as of Monday. LONDON, July 29 (UPI) -- A third consecutive finals appearance has Fabio Fognini at a career high No. 16 in the ATP rankings. Fognini hadn't won an ATP tournament until July 14 when he took the event in Stuttgart. He followed that the next week with a title in Hamburg. Last week he reached the final of the Croatia Open. Even though Tommy Robredo broke Fognini's 13-match winning streak in the championship match, Fognini moved up in the rankings. He was 31st when his streak started. Robredo's 12th ATP title -- and second this year -- improves his ranking five places to No. He's won the last six times he's reached a tournament final. The week's other champions also move up. John Isner, who claimed the BB&T Atlanta Open with an epic 6-7 (3-7), 7-6 (7-2), 7-6 (7-2) decision over Kevin Anderson, moves up two to 19th. Mikhail Youzhny, whose win at the Swiss Open was his ninth title, goes from 33rd to No. There was no change in the Top 10 in Monday's update. 7-ranked Juan Martin del Potro, the top seed at the Citi Open in Washington, is the only Top 10 player entered in a tournament this week. Tommy Haas, last year's runner-up in Washington, returns to that tournament, as does champion Alexandr Dolgopolov. That means Haas won't be in Austria where he was the two-time defending champion of the bet-at-home Cup Kitzbuhel. A change in the ATP calendar has the events the same week.
