Juan Martin del Potro has recorded a shock second-round win to knock fourth seed Stan Wawrinka out of the men's singles at Wimbledon.
Del Potro secured a 3-6 6-3 7-6 (7-2) 6-3 victory over the Swiss player.
The Argentine is 165th in the rankings after missing more than two years because of injury problems.
Del Potro, who is in the same half of the draw as Britain's Andy Murray, will next play either France's 32nd seed Lucas Pouille or American Donald Young.
Former US Open champion Del Potro, 27, reached the Wimbledon semi-finals in 2013 but the former world number four is playing in his first Grand Slam since the Australian Open in 2014 after having three wrist operations.
