Lleyton Hewitt turned his attention to Wimbledon after being knocked out of this year's AEGON Championships at Queen's by Ivo Karlovic.
Hewitt underwent major foot surgery last month in a bid to prolong his career and was looking to help his recovery by having a good run at the Wimbledon warm-up tournament in west London.
The former SW19 champion was handed a tough draw against 6ft 10in Karlovic, however, and the Croatian went on to record an easy 6-3 6-2 win.
Hewitt admitted he was disappointed to have drawn Karlovic, who sent down 22 aces in nine service games en route to victory, but his mood improved after hearing he had been granted a wild card by the All England Club for Wimbledon afterwards.
"It's not really a tennis match in some ways when you're playing against a guy like Karlovic," the 31-year-old said.
"It was just one of those days today, but I am excited about Wimbledon now.
"After the surgery Wimbledon was always the focus. It's the best tournament there is."
Hewitt has had struggled with injury for a large part of the 10 years that have passed since he won Wimbledon and Novak Djokovic and Rafael Nadal seem a class apart from the rest of the field on all surfaces, but Hewitt is confident he can ruffle a few feathers at Wimbledon next month.
He said: "It would have been nice to get a couple of matches under my belt, but, if there's one place you feel like things can open up for you, it's probably there for me.
"Obviously the top few guys are way above everyone else right at the moment, but if you can put yourself in a moment to go out there - and I still feel like if I'm hitting the ball as well as I can be and moving well - then I can still put some pressure on a lot of the guys in the draw."
