Andy Murray said he would keep trying to win Grand Slams after crashing out of the US Open second round in straight sets to 15th seed Felix Auger-Aliassime.
The former world number one was demolished by the 20-year-old Canadian 6-2, 6-3, 6-4 inside Arthur Ashe Stadium in 2hr 8min.

But Murray said he was pleased with how his metal hip coped in his first Grand Slam outing since the 2019 Australian Open, when there was talk of him retiring.
“I’m more positive about what I can do in Grand Slams before I came over here,” said Murray who rallied to a win thrilling five-set match against Japan’s 49th-ranked Yoshihito Nishioka in the first round on Tuesday.
The Scotsman is trying to rebuild his career after an injury-ravaged three years, and currently sits 115th in the world rankings.
“I feel like I’m back at square one having not played Slams for a few years,” Murray, a three-time Grand Slam winner, told reporters.
“I need to build up my body and my physical conditioning so that, you know, I have the ability to back up five-set matches.
“That takes a bit of time, unfortunately.”
