The Frenchman will now face either Novak Djokovic or Kei Nishikori for a place in the final following his first win over the Canadian in four attempts.

Their quarter-final gets under way at 08:30 GMT.

The other men's semi-final will be between 17-time major winner Rafael Nadal and Greece's Stefanos Tsitsipas.

"I did really great with returns and kept my serve almost all the match," said 28th seed Pouille, whose coach Amelie Mauresmo worked with Andy Murray from 2014 to 2016.

"I did not win a match before coming here, now I'm in the semi-final so I'm really happy.

"We kept working hard - even after all the matches I lost in the Hopman Cup. I decided to take it step by step and give it all I have on every single point."

Pouille entered the world's top 20 in 2016 after reaching the last eight at Wimbledon and US Open. However, he struggled in 2018, failing to progress past the third round of any of the majors.

Coming into this match, the 24-year-old had lost his only match at the Sydney International and his three singles rubbers at the recent Hopman Cup.

When he trailed Raonic 5-2 in the first set, it appeared that the Frenchman was set for another defeat in Australia, but he fought back to not only level the scores but then take the tie-break.

Pouille grew in confidence and broke the 2016 semi-finalist in the fourth game of the second set with a superb lob en route to establishing a two-set lead.

The contest swung back towards the Canadian in the third set as he saved four break points before sweeping aside Pouille in a one-sided tie-break.

The fourth set went with serve until the 10th game when Raonic, after saving three match points, sent a volley wide to hand Pouille victory.

"I really wanted to return as well as possible and make him play. I've taken care of my serve and did not put too much pressure on myself," added Pouille.

"We had a plan and every single point I stayed focused and stayed on the plan we decided yesterday - it was a great match."
