Juan Martin del Potro partied like it was 2009 to beat Roger Federer in the US Open semifinals and deny New York the Nadal vs. Federer clash it craved. 

Afterwards, Telegraph Tennis Correspondent Simon Briggs joined Tennis Podcast presenter David Law to talk about where it all went right for the Argentine and wrong for the five-time champion. 

Federer squandered four set points in the third set tie-break with the match tied at one set all. Did he choke? 

Given Del Potro had nearly retired a two sets down against Dominic Thiem in the previous round, how on earth has he reached the semifinals?

New York will be devastated to have missed out on a Nadal - Federer clash. Nadal kept his side of the bargain by beating Andrey Rublev in straight sets, but Del Potro had other ideas. Twice before Federer had fallen short when he held match points against Novak Djokovic in the 2010 and 2011 semifinals, with Nadal already in the final. Will it ever happen?

And, with Venus Williams vs. Sloane Stephens and Madison Keys vs. Coco Vandeweghe, America is guaranteed an all-American semifinal line-up for the first time in 36 years. Law and Catherine Whitaker discuss. 

Plus, with Andy Murray announcing that his season is all but over, we hear from Mats Wilander on whether it's the right decision.
