Top seed Juan Martin del Potro made short work of Marcos Baghdatis as he progressed to the quarter finals of the Swiss Open in Basel. The grand-slam winning Argentine now sets up a quarter final showdown against French qualifier Paul Henri Mathieu who was a surprise winner against compatriot Michael Llodra. Also advancing is Bulgaria's Grigor Dimitrov who is paired against home favorite Roger Federer in the last eight. Federer still needs ranking points to make the season-ending world tour finals in London. – ANC Dateline Philippines, October 25, 2013
