Frenchman up to world No.7 after title triumph

Jo-Wilfried Tsonga took a giant step towards cementing his place at the season-ending ATP World Tour Finals after coming from behind to beat Juan Martin Del Potro in the final of the Erste Bank Open in Vienna. Top seed Tsonga found himself a set and a break down but rallied to record a 6-7 (5/7) 6-3 6-4 triumph on Sunday. The victory, Tsonga's second of the season and seventh overall, lifts the Frenchman up to seventh in the world rankings with the world's top eight qualifying for the ATP finals in London. Former US Open champion Del Potro, who is now 9-4 in career finals, is still waiting for his first victory at an indoor event. Del Potro looked to be in control of the match after winning the opening set on a tie-break and breaking for a 2-1 lead in the second, but Tsonga reeled off four straight games on his way to levelling the contest. In the final set, Tsonga stepped up on serve, firing nine of his 25 aces to win 80 per cent of his service points. He broke his Argentinian opponent in the seventh game and closed out the match with a love service game. "That was really tough," said Tsonga. "Juan Martin played very well. "I lost a little motivation after losing the first set but fortunately I got it back quickly."
