TORONTO — Greek teen Stefanos Tsitsipas became the youngest player to beat four straight top-10 players in an event since the ATP World Tour was established in 1990, outlasting Kevin Anderson 6-7 (4), 6-4, 7-6 (7) on Saturday to reach the Rogers Cup final.
Tsitsipas, who will be 20 on Sunday, will face the winner of the late match between top-ranked Rafael Nadal and Karen Khachanov.
Tsitsipas beat the fourth-seeded Anderson after topping seventh-seeded Dominic Thiem, ninth-seeded Novak Djokovic and second-seeded defending champion Alexander Zverev to reach his first ATP World Tour Masters 1000 semifinal.
Tsitsipas fired an ace at 7-7 before converting his third match point of the deciding tiebreaker when Anderson’s return sailed long. The South African had a match point of his own at 7-6, but Tsitsipas came through with a brilliant backhand crosscourt winner to pull even.
The 32-year-old Anderson reached the Wimbledon final last month.
He also lost his only other match against Tsitsipas, falling this year on clay in Portugal.
Tsitsipas will jump from 27th to 15th when the new rankings are released Monday.
