LONDON - Roger Federer reached his 50th Grand Slam quarter-final and 15th at Wimbledon on Monday with a 6-4, 6-2, 6-4 win over Grigor Dimitrov.
Seven-time Wimbledon champion Federer will face either Canada's Milos Raonic, the sixth seed, or German 10th seed Alexander Zverev for a place in the semi-finals.
Raonic defeated Federer in the semi-finals at Wimbledon in 2016.
Federer, 35, is also the second oldest man to make the quarter-finals at Wimbledon behind Ken Rosewall who was 39 when he reached the last-eight in 1971.
"I'm thrilled to be back in the quarters again," said Federer who took his record over Dimitrov to 6-0.
"It's very special to be in a 15th quarter-final here."
Meanwhile, Sam Querrey booked a shot at Andy Murray in the Wimbledon quarter-finals with a five-set victory over Kevin Anderson on Monday.
The US 24th seed beat the unseeded South African 5-7, 7-6 (7/5), 6-3, 6-7 (13/11), 6-3.
After making it through the fourth round for the second straight year - equalling his best-ever Grand Slam performance - he faces world number one Murray, the defending champion, in Wednesday's last eight.
Querrey famously dumped Novak Djokovic out of Wimbledon in the third round last year.
