GLASGOW'S Jamie Baker is focused on Wimbledon after crashing out of the Nottingham Open in the first round this afternoon.

Baker, 20, was beaten 4-6, 2-6 by Argentinian Juan Martin Del Potro, despite plucky resistance from the British No.6.

Del Potro, who is ranked at No.55 in the world and stands almost 200 places above Baker, broke in the final game of the first set to take the lead after the first nine games went with the serve.

But, while Del Potro continued to dominate his own serve, Baker had to work a lot harder to keep his service games.

And the pressure finally started to show on Baker as he was broken on his first service game in the second set, allowing Del Potro to race into a 3-0 lead.

Baker hit back with two love service games, but the South American stayed in control to see off the young Scot.

"It was tough test for me, but I'm quite disappointed because I thought I could do a lot better," said Baker.

"Barring the top 20 players in the world, there are not too many players better than he is.

"I was right up there with him in the first set and even in the second set, but it was my mistakes that gave him the chance. Someone ranked that high is too good to give that many opportunities to.

"There is definitely more to come from me. Today was a case of making the most of matches like this because, ranking wise, I can't get competition like this week-in, week-out.

"Most people will say Wimbledon is the biggest tournament in the world. Last year I wasn't too sure what to expect from Wimbledon because I'd never done it before.

"But I'm confident of putting in a better performance on the court this time compared to last year."

Meanwhile, Alex Bogdanovic became the first player to exit after falling to Guillermo Garcia-Lopez in the first round.

Resuming a set down after yesterday's rain delay, the British No.3 had eight chances to force a deciding set in a marathon tie-breaker before losing 4-6, 6-7 (13-15).

There was nothing to choose between the pair as the second set went with serve to force a tie-breaker.

It was Bogdanovic who had the best chances with the net cord once coming to Garcia-Lopez's rescue, but his double fault on the 25th point handed his opponent the match.

And there was more bad news for the Brits as national No.5 Joshua Goodall lost 5-7, 3-6 to Russian Teimuraz Gabashvili.

Jamie Murray and Eric Butorac beat British No.2 James Auckland and Stephen Huss 6-4, 7-6 (7-5) in their first-round tie.
