Juan Martin del Potro sensationally gatecrashed the US Open again on Wednesday, stunning five-champion Roger Federer and shattering hopes of a first New York showdown between the Swiss legend and Rafael Nadal.
The Argentine giant, who won his only Grand Slam title in the city in 2009 by beating Federer in the final after seeing off Nadal in the semis, triumphed 7-5, 3-6, 7-6 (10/8), 6-4 in front of a spellbound Arthur Ashe Stadium crowd.
The 28-year-old will once again face world number one Nadal in the semi-finals on Friday, a stunning achievement for a man who had saved two match points to beat sixth seed Dominic Thiem in the last 16.
