Kyle Edmund powered into a first Grand Slam quarter-final with a four-set win over Italy's Andreas Seppi at the Australian Open.
The British number two, ranked 49th, recovered from a slow start to win 6-7 (4-7) 7-5 6-2 6-3 at Melbourne Park.
Edmund, 23, trailed by a set and a break but hit 25 aces and cut down on early errors as he went on to dominate.
He will face Australian Nick Kyrgios or Grigor Dimitrov of Bulgaria in the last eight on Tuesday.
Edmund is the only British man other than Andy Murray to reach the quarter-finals in Melbourne since John Lloyd in 1985.
