NEW YORK: Defending champion Rafal Nadal failed to win a single game in the opening set of his U.S. Open quarter-final against Dominic Thiem on Tuesday but fought back to beat the Austrian 0-6 6-4 7-5 6-7(4) 7-6(5) in the match that ended past 2 a.m. in New York.
Nadal won just 40 percent of his first serves in the first set as he struggled with the high humidity on the Arthur Ashe Stadium court, as Thiem became the first player to 'bagel' the Spaniard at Flushing Meadows since Andy Roddick 14 years ago.
"It's been a great battle," an exhausted Nadal said. "The conditions were tough, very humid for me."
Thiem, who lost to Nadal in the French Open final but who has beaten the Spaniard three times in 10 previous meetings, struck 74 winners, including 24 with his stylish single-handed backhand, to keep the champion under constant pressure.
"I'm very sorry for Dominic," Nadal added. "He's a close friend on tour, a great guy and I wish him the very best ... He is young and has plenty of time to win tournaments."
After Nadal roared back to take a 2-1 lead, the fourth set went to a tiebreak. Thiem raced to a 3-0 lead before Nadal fought back, but the Austrian held his nerve to level the match.
There were no breaks of serve in the deciding set and a second tiebreak ensued. The two were neck-in-neck at 5-5 when Nadal carved out a match point with his forehand.
Thiem's wayward overhead smash handed the match to Nadal, who stood midcourt with his head thrown back and arms raised in the air in celebration.
"Thank you very much, everybody, for staying here tonight," Nadal said after the four hours, 49-minute marathon.
"It's been an amazing feeling. I'm playing a lot of hours this year at this beautiful stadium."
Next up for the top seed is a semi-final clash with big-serving Argentine and third seed Juan Martin del Potro.
