Giovanni Mpetshi Perricard completed a perfect week on serve by upsetting American Ben Shelton to win the Swiss Indoors on Sunday. The French player, who is ranked No. 50, prevailed 6-4, 7-6 (4) against the sixth-seeded Shelton to become the lowest-ranked champion since the tournament became a tour-level event in 1975. Mpetshi Perricard did not drop serve all week in Basel, winning all 60 of his service games and having to fend off just three break points — all in his quarterfinal match against Denis Shapovalov.
