 Rafael Nadal -01- (ESP) def  Dominic Thiem -09- (AUT) | 06 64 75 67(4) 76(5)
Absolute heartbreaker for Dominic Thiem, who is making a habit of soul-crushing defeats at the US Open.
Last year on Grandstand, Thiem was easily up 2-sets on a very ill Juan Martin Del Potro. Somehow, the Argentine launched a tremendous comeback to earn the 4th-Round win 16 26 61 76(1) 64. For the fourth time, Thiem was sent home before the Quarterfinals.
This year, after a tough battle with 2017 Finalist and World #5 Kevin Anderson, Thiem finally won four matches in Flushing. He got another stab at World #1 Rafael Nadal – his opponent in the championship match at Roland Garros 3-months prior (Nadal won 64 63 62).
Tonight was huge – an opportunity to face Rafa on a faster surface – a chance to prove to himself he could usurp one of the greatest to play the game at a Slam.
And man, did he start-off brilliantly. Thiem allowed Nadal only 7 POINTS during the entire first set. Fans in Ashe were stunned. The last time Rafa was “bageled” in a first-set, he went-on to defeat Philipp Kohlschreiber in the 3rd-Round of the 2017 Miami Open.
And Nadal did it again tonight, recovering from that horrendous first set to defeat Thiem at 2:04am – after 4-hours and 49-minutes, the longest match Nadal has ever played at the US Open. Sadly, the nearly 5-hour match came down to one critical Thiem mistake when it mattered most. Down 5-6 in the deciding-set tiebreak, he missed an overhead – and lost the match.
Again – absolute heartbreaker for the Austrian. Meanwhile, 3-time US Open Champion (2010 | 2013 | 2017) Rafael Nadal is through to his 29th Grand Slam Semifinal, 7th at the US Open.
