In a gripping 4-hour 49-minute contest which concluded at 2.04 a.m. on Wednesday, world number one Nadal won through to keep his bid for a fourth title in New York and 18th Grand Slam crown on track.
Defending champion Rafael Nadal survived an epic US Open quarter-final confrontation to defeat battling ninth seed Dominic Thiem 0-6, 6-4, 7-5, 6-7 (4/7), 7-6 (7/5) and reach the semi-finals for the seventh time.
In a gripping 4-hour 49-minute contest which concluded at 2.04 a.m. on Wednesday, world number one Nadal won through to keep his bid for a fourth title in New York and 18th Grand Slam crown on track. However, the 32-year-old was fortunate to triumph on another hot and humid night at Flushing Meadows, 24 hours after Roger Federer had been dumped out of the tournament by John Millman.
After suffering a first set 'bagel', Nadal had to battle back from breaks in the third and fourth sets before seeing off the first top 20 player he had faced at the US Open since 2013. "I suffered, that's the right word," said Nadal after playing his longest ever match at the tournament. "I said to Dominic I am sorry. He's a great guy, a close friend who will have many more opportunities to win the big titles."
Nadal had defeated Thiem in the Roland Garros final in June but this was their first meeting away from a clay court. "He has a great attitude and is a great fighter," added Nadal.
In a dramatic final set, Nadal saw five break points come and go before Thiem went long with a smash on the first match point. It was his 58th unforced error on a night when he sent down 18 aces and fired 74 winners.
The semi-final will pit Nadal against third seed Juan Martin del Potro for the second successive Grand Slam. At Wimbledon, Nadal came back from two sets to one down to win in five in a quarter-final which stretched to almost five hours.
Thiem broke three times in a 24-minute first set on Tuesday, handing Nadal just his third 'bagel' at a Grand Slam. The top seed won just seven points in the opener. "I told myself 'wake up'," said Nadal.
Nadal recovered from being broken as he served for the second set in the ninth game with an immediate break back to level the contest. Thiem then grabbed a 4-3 lead in the third which he stretched to 5-3 but then it was his turn to crack as Nadal raced away with three games to claim a two sets to one lead.
Thiem was 4-2 ahead in the fourth set before he was again reeled in and he was two points from defeat in the 12th game. But he took the tiebreaker before Nadal just proved the steadier of the two in the final set decider.
Meanwhile, Thiem said his epic defeat to close friend Nadal i will "stay with me forever".
"It's going to be stuck in my mind forever. Forever I'm going to remember this match, for sure," said Thiem after his first ever hard court match against Nadal. "Tennis is cruel sometimes because I think this match didn't really deserve a loser. But there has to be one. It ended up in the fifth set tiebreaker, there it's 50/50. He made one more point than me."
Thiem handed Nadal, against whom he lost in the Roland Garros final in June, just his fourth ever 'bagel' set at the Slams. That was wrapped up in just 24 minutes with Nadal winning only seven points. Thiem was also 5-3 ahead in the third set and 4-2 in the fourth before he was reeled in by Nadal, the three-time champion in New York.
Nadal said he had told Thiem he was sorry for the result although the Austrian laughed off that consolation from his close friend. "I don't think he's really sorry," said the 25-year-old. "I mean, he's a great guy. I don't want to lose against anybody. But now I wish him the title the most, that's for sure. I think we almost all the time have great matches. I hope that we have many more in the future -- with a different end."
The semi-final will pit Nadal against third seed and 2009 US Open champion Juan Martin del Potro for the second successive Grand Slam tournament. At Wimbledon, Nadal came back from two sets to one down to win in five in a quarter-final which stretched to almost five hours.
