New York: A weary Stanislas Wawrinka of Switzerland was disappointed to fall short of his first grand slam semi-final appearance on Thursday but took comfort by his string of success at the US Open.
Wawrinka, who had logged the most court time of any of the quarter-finalists after taking 12 hours 27 minutes to get through his first four matches, fell 3-6, 7-6, 3-6, 6-3, 6-3 to 12th-seeded Russian Mikhail Youzhny.
The hard-hitting Swiss said he had learned a lot on court at the US Open.
"Just after the match it`s always difficult," he said. "But I think today Mikhail was playing very good. I tried my best. I tried to fight on all the match, but was too much."
The 25th seed reached his first grand slam quarter-final with a four-hour 38-minute, five-set victory over 20th-seeded American Sam Querrey after eliminating fourth seed Andy Murray in four sets that took nearly four hours of work.
"I think I give everything today, and I try, I try, for sure," the 25-year-old said. "I made some big mistakes, but after four hours you`re really tired. I was tired."
After losing in the first round of the US Open last year, Wawrinka said he would take a lot from his rousing run.
"If I go back, I`m very pleased with the tournament," he said after bowing out in another four-hour struggle. "I know especially against Andy Murray was I think my best match, and I was playing really, really strong," he said about the 6-7, 7-6, 6-3, 6-3 win against the fourth-seeded Briton.
"For the rest of the season and for sure next year, it`s gonna be, I hope, more tournaments with that level."
A tiring Wawrinka conceded his tactics and behavior were not always his best, referring to a few ill-timed drop shots he floated over the net that turned into winners for Youzhny and the rackets he slammed to the court in frustration.
"It`s not always easy to think and to play the right drop shots or to play the good point and not to break the racket," he said. "But after the match, I just know that I try everything. I think he was just a little bit better today."
