Vienna:Andrey Rublev advanced to his fifth final of the season Saturday after Kevin Anderson pulled out in the second set of their semifinal at the Erste Bank Open.
The fifth-seeded Rublev led 6-4, 4-1 when Anderson quit the match with a right thigh issue.
In Sunday's final, Rublev will play Daniel Evans or Lorenzo Sonego, who beat Novak Djokovic 6-2, 6-1 in Friday's quarterfinals.
Anderson, who won the event in 2018, wore tape on his thigh from the start of the match. He first got a medical timeout after losing the opening game of the second set and asked for treatment again at 3-0 before playing just two more games.
It was the second time this week that Rublev's opponent quit their match, after Jannik Sinner pulled out after three games with a foot injury in the second round.
The eighth-ranked Rublev is 4-0 in finals in this shortened season and can become the first player with five tournament wins.
