On-fire Andrey Rublev powiered into his fifth final of 2020 as opponent Kevin Anderson was forced to retire with a right leg injury on Saturday at the Vienna ATP event.
Only a day after the quarter-final exits of top seed Novak Djokovic and Austrian holder Dominc Thiem, 2018 champion Anderson had to quit trailing 6-4, 4-1 after 62 minutes.
Eighth-ranked Rublev will wait for an opponent as Brit Dan Evans plays Lorenzo Sonego – quarter-finals conqueror of Djokovic – in the second semi-final at the Stadthalle in front of a limited 1,000 spectators due to COVID-19 restrictions.
Rublev, who leads with Djokovic on four titles this season, has yet to lose a set this week as he bids to add another trophy to his resume.
The 23-year-old has won 18 of his last 19 matches,
Rublev is holding onto the eighth and final spot in the the race for the eight-man ATP Finals in London from November 15 with a challenge from Argentine Diego Schwartzman one spot behind.
“I don’t know why it’s going so well,,” the winner said. “But I have an amazing team and amazing friends around me who always support me.
“Probably that’s why I’m playing so well. I came here thinking that I have nothing to lose.
“I came to fight for every point, every match, and now here I am in the final.”
Rublev fired 11 aces against the big-hitting Anderson, who managed six and lost his serve twice; the South African handed over a double-faults on set point in the opener.
An injury timeout after the first game of the second set proved to be the end for the 34-year-old who once stood fifth but ranks outside the Top 100 after a season or more of knee injuries.
