British qualifier Chris Eaton continued his impressive form by beating Serbia's Boris Pasanski in straight sets to reach the second round at Wimbledon.

The 20-year-old from Surrey hammered down 26 aces to overpower the world number 114 on Court Three.

Eaton, ranked 661st, held his serve throughout and broke Pasanski twice to claim a 6-3 7-6 (8-6) 6-4 victory.

But fellow Briton Jamie Baker tumbled out in the first round, losing 6-4 6-2 6-3 to Italy's Stefano Galvani.

Baker, whose progress this year has been held back by a rare blood disease, trailed 3-1 in the first set but led 4-3 before Galvani rallied, and the Scot never regained a foothold in the match.

Eaton, who had to beat six opponents just to make the main draw, was making his Wimbledon debut but was not overawed despite the presence of a sizeable crowd to cheer him on.

The crowd played a massive part for me. When you first walk out on court, with their backing you cannot not give everything yourself Chris Eaton

Pasanski, who lost to Andre Agassi in the first round on his only previous appearance here in 2006, never looked comfortable on grass and Eaton took full advantage.

The Serb's frustrations grew in the final set when he argued a series of line calls, while Eaton kept his cool to complete his win with a decisive break at 5-4 up.

"It feels pretty good," Eaton said afterwards. "The way I was playing and serving, I knew I had a chance.

"I can remember quite a lot of the match. There were times I was holding my serve quite easily and not getting much back on his - those games fly past quite quickly but you wake up at 4-4."

Eaton appreciated the backing of a vocal crowd but said just being at Wimbledon was enough to motivate him.

"The crowd played a massive part for me," he explained. "When you first walk out on court, with their backing you cannot not give everything yourself - it is amazing how much they can lift you.

"But it is not so much the crowd as in playing here. Wimbledon is the big tournament and the one I like the most - there is no problem getting yourself up to play here."

Eaton faces 25th seed Dmitry Tursunov, who beat Tim Henman in five sets at Wimbledon in 2005, in round two on Thursday.

"It should be a pretty good match," Eaton added. "I have watched him play on TV before so I know what to expect."
