BASEL, Switzerland — Third-seeded Stefanos Tsitsipas advanced to his 13th quarterfinal of the season by beating Ricardas Berankis 6-7 (4), 6-2, 6-4 at the Swiss Indoors on Thursday.
The seventh-ranked Tsitsipas conceded just a single break point against the 70th-ranked Lithuanian.
Earlier, fourth-seeded Roberto Bautista Agut’s 6-2, 4-6, 6-3 win over Richard Gasquet also earned him a 13th quarterfinal in 2019, joint best on the tour.
Hard-serving American Reilly Opelka upset sixth-seeded David Goffin 6-7 (4), 7-6 (4), 7-5 with the help of 29 aces.
In the deciding set, Opelka used his one break point of the match to force the only service break in any of the five sets he has played in Basel this week.
