BASEL, Switzerland — Marin Cilic and Juan Martin del Potro will face each other in the Swiss Indoors semifinals after both were tested in three-set wins on Friday.
Second-seeded Cilic was on court for more than three hours to beat 100th-ranked qualifier Marton Fucsovics of Hungary 7-6 (3), 5-7, 7-6 (4).
Cilic, the defending champion at Basel, clinched the quarterfinal with a delicate sliced backhand volley for a winner.
Fourth-seeded Del Potro needed exactly two hours to win 6-2, 2-6, 6-4 against sixth-seeded Roberto Bautista Agut of Spain.
Del Potro won back-to-back Basel titles in 2012 and ’13, both times beating Roger Federer in the final.
The Argentine will qualify for the ATP Finals in London if he wins the title in Basel
Federer, top-seeded again at his hometown event, played later Friday against Adrian Mannarino of France.

MADRID — Andy Murray will play in a second-tier Challenger Tour tournament hosted by Rafael Nadal’s tennis academy.
The tournament says Murray has accepted an invitation to play.
Murray, a three-time Grand Slam champion, had hip surgery in January. He returned to the court in June playing doubles – including at Wimbledon – before moving back to singles this month. The former No. 1 lost to Richard Gasquet in Cincinnati and to Tennys Sandgren in Winston-Salem, both in the first round.
Murray has not played on the Challenger Tour since 2005. His opener at the tournament in Mallorca, Spain, will be his 35th match in the lower division.
The tournament starts on Aug. 26.
