Tokyo, Japan: Local favourite Kei Nishikori thrashed fifth seed Stefanos Tsitsipas 6-3, 6-3 to reach the Japan Open semi-finals on Friday, edging him closer to a third Tokyo title.
Third seed Nishikori, who won the last of his 11 career titles in Memphis two years ago, made light of the danger posed by the young Greek with a ruthless victory in just 82 minutes.
After winning the Japan Open in 2012 and 2014, Nishikori will face the winner of the late match between second seed Kevin Andreson or France's Richard Gasquet as he looks to advance to the final for the third time.
Nishikori broke Tsitsipas for a second time to nudge ahead 4-3 before closing out the first set with an acrobatic backhand volley.
The world number 12 quickly took a 4-1 lead in the second as the potential threat of a swashbuckling opponent ranked only three places below him never materialised.
Having failed with his first two match points, it was third time lucky for Nishikori, who delivered the coup de grace by whipping a forehand past a deflated Tsitsipas to the delight of a sellout crowd.
"I played well from start to finish," said Nishikori, a former US Open runner-up who reached New York semi-finals last month.
"I was returning well, which meant I could serve relaxed," added the 28-year-old, who is chasing a first title since recovering from a lengthy wrist injury.
"I was picking the ball up early, seeing it big and being aggressive. Hopefully now I can go even further."
Earlier, Canada's Denis Shapovalov, who last year made unwanted headlines after smashing a ball at an umpire and fracturing his eye socket during a Davis Cup tie, squeezed past German Jan-Lennard Struff 4-6, 7-6 (9/7), 6-4.
Sixth seed Milos Raonic, a three-time Tokyo finalist, crashed out in straight sets, the big-serving Canadian toppled 7-6 (7/4), 6-3 by Russian qualifier Daniil Medvedev.
