Juan Martin del Potro edged closer to a spot at next month's ATP Finals as the fourth seed dispatched French qualifier Julien Benneteau 6-4, 6-4 to reach the Swiss Indoors quarter-finals on Thursday. Del Potro won the Basel title in 2012 and 2013, beating seven-time champion Roger Federer in both of those finals. "I'm tired, but I'm still winning and playing good tennis," the world number 19 said. "This keeps me motivated to keep going.
"I have good chances to go far here and also rise in the rankings. I face a tough opponent tomorrow (Roberto Bautista Agut), so we will see what will happen. "I played better than yesterday, but tomorrow I need to improve a little bit more. Bautista is one of the toughest guys, it will be a high-level match." The Argentinian is 14th in the standings with only two weeks remaining in the race to the eight-man season-ending tournament in London.
But with Andy Murray, Novak Djokovic and Stan Wawrinka not playing for the rest of the season due to injury, the South American's position is looking stronger and stronger.
