America's Andy Roddick booked his place in the Wimbledon quarter-finals on Monday with a 6-3, 7-6 (7/1), 6-4 win over Argentina's Guillermo Coria.
Roddick, the second seed, now faces either French ninth seed Sebastien Grosjean or Russia's Dmitry Tursunov for a place in the semi-finals.
"I'm playing fine," said Roddick.
"I'm in the quarter-finals, hitting the ball well. I got through a couple of tough situations today so I feel good."
Roddick also opted for a new approach by trying to volley more than in previous matches.
"It was part of my plan to get to the net more today. He was missing a little off the first serve, missing from the baseline so I put pressure on him and I did that well."
The 22-year-old American, the runner-up to Roger Federer here last year, eased through the first set in just 35 minutes with a break in the fifth game.
Coria, whose eight career titles have all come on clay, recovered from an early break in the second set to force the tiebreak which Roddick dominated behind his signature big serve.
Roddick again edged ahead to 2-0 in the third set but, to his credit, the Argentinian 15th seed battled back to 3-3 before again slipping behind in the seventh game.
