| Nadal won 40 percent of his first serves in the 
				opener as he struggled with the high humidity on Arthur Ashe 
				Stadium court, with Thiem becoming 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 had 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.
 
 "It's going to be stuck in my mind forever," Thiem said.
 
 "I'm going to remember this match, for sure. It's cruel 
				sometimes tennis, because I think this match didn't really 
				deserve a loser. But there has to be one.
 
 "If we skip the first set, it was a really open match from 
				beginning to the end. The way it ended up in the fifth set 
				tiebreaker, from there it's 50-50. He made one more point than 
				me."
 
 Nadal paid tribute to the crowd for hanging on until the early 
				hours of Wednesday morning.
 
 "Thank you very much everybody for staying here tonight," Nadal 
				said after the four hour, 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.
