Beating his second top-10 opponent this week, 93rd-ranked Marius Copil reached the Swiss Indoors final by stunning Alexander Zverev 6-3, 6-7 (6), 6-4 on Saturday.
The Romanian will play for a first career title on Sunday against top-seeded Roger Federer or seventh-seeded Daniil Medvedev.
Copil fired 26 aces past Zverev and never dropped serve, clinching after 2 1/2 hours with a forehand volley winner to break the fifth-ranked German’s serve for the second time in the semifinal.
Copil came through two rounds of qualifying last weekend to reach the Basel main draw, including beating Zverev’s older brother, Mischa.
In the second round, Copil beat sixth-ranked Marin Cilic for his first career win against a top-10 player.
