In the 2011 US Open men's doubles final, he arguably had his greatest success of the year when he and his doubles partner Philipp Petzschner won a controversial decision over the Polish team of Mariusz Fyrstenberg and Marcin Matkowski to claim the trophy. During a net exchange, a ball ricocheted off Petzschner's left shin, though he denied it. Instant replay of the telecast clearly confirmed the illegal return. Jurgen/Petzschner broke through in that game and won the match in straight sets, splitting a $420,000 purse.
