Unheralded Spaniard Guillermo Garcia-Lopez caused the biggest shock of the French Open when he knocked out Swiss third seed Stan Wawrinka 6-4, 5-7, 6-2, 6-0 on Monday. The Australian Open champion, who was tipped as a possible champion in Paris, struggled throughout in a mistake-strewn performance that saw him produce 61 unforced errors. Garcia-Lopez, who came into the tournament ranked 41 in the world, was unfazed by the occasion as he booked a second round match against Frenchman Adrian Mannarino. Source: AFP
