Brazil's Thiago Monteiro, ranked 85th in the world, upset World No. 9 Casper Ruud 6-3, 6-3 in the second round of the Nordea Open on Wednesday in Bastad, Sweden. It was Monteiro's first win against Norway's Ruud in four matches. Seeded second, Ruud had more aces (7-2) but forced only one break point and didn't covert. Monteiro was 3 of 6 on break-point conversions and fired more winners, 32-19. Top-seeded Andrey Rublev of Russia, the No. 8 player in the world, faced Argentina's Thiago Agustin Tirante later Wednesday. Croatian qualifier Duje Ajdukovic knocked off eighth-seeded Pavel Kotov of Russia 7-6 (7), 3-6, 6-3, and Spain's Roberto Carballes Baena also went three sets to eliminate Kazakhstan qualifier Denis Yevseyev 2-6, 6-3, 6-2. Hamburg Open A lingering knee injury didn't prevent defending champion Alexander Zverev from cruising past Jesper de Jong 6-2, 6-2 in the opening round in Germany. Playing in his home country, top-seeded Zverev has a bone edema and tear in the capsule in his left knee resulting from a fall in a third-round win over Cameron Norrie at Wimbledon. Zverev, ranked No. 4 in the world, did not face a break point, converted 4 of 5 break-point opportunities and had far more winners (29-6) against de Jong of the Netherlands.

Swiss Open Gstaad Top seed Stefanos Tsitsipas of Greece saved all five break points in defeating Hamad Medjedovic of Serbia 7-6 (6), 6-3 in the second round in Switzerland. Tsitsipas powered 11 aces and won 13 of 18 (72.2 percent) net points, to 5 of 15 (33.3 percent) for Medjedovic. Fourth-seeded Tomas Martin Etcheverry of Argentina was a 6-2, 2-6, 6-3 winner over Botic van de Zandschulp of the Netherlands; fifth-seeded Jan-Lennard Struff of Germany won a battle with Switzerland's Leandro Riedi 7-6 (6), 7-6 (1); and seventh-seeded Fabio Fognini of Italy rallied past Peruvian qualifier Juan Pablo Varillas 3-6, 7-6 (5), 7-5. Infosys Hall of Fame Open Reilly Opelka fired 19 aces to just one double fault in upsetting top seed Adrian Mannarino of France 6-4, 3-6, 6-4 in the second round in Newport, R.I. The 6-foot-11 American wild card recorded more winners (37-12) with a maximum service speed of 141 mph. Each player converted two break points.
