Jordan Thompson upset ninth-ranked Alexander Zverev 6-3, 6-4 in the opening round of the Japan Open on Monday for his second win over a top-10 opponent this season.
The 29-year-old Australian saved four of the five break points he faced to claim his first career win over Zverev after losing their only previous meeting six years ago. He also beat seventh-ranked Stefanos Tsitsipas at Indian Wells in March.
“I fought off 0-40 first game and I really got into the match after that,” the 60th-ranked Thompson said. “But I held on, I was playing an unpredictable style of tennis, and I think he didn’t handle it that well in the first set and adapted in the second. But I somehow hung around.”
Thompson will next play either Shanghai Masters semifinalist Ben Shelton or qualifier Taro Daniel.
The other three Australians in action Monday all lost as eighth-seeded Felix Auger-Aliassime defeated Aleksander Vukic 7-6 (3), 6-7 (2), 6-2, while Mackenzie McDonald beat Max Purcell 7-5, 6-4 and Sebastian Ofner outlasted Christopher O’Connell 6-7 (2), 7-6 (5), 7-5.
Fifth-seeded Tommy Paul plays Daniel Altmaier in a late match.
Top-seeded Taylor Fritz plays his first-round match against Cameron Norrie on Tuesday, while second-seeded Casper Ruud meets wild-card entry Yosuke Watanuki.
Shanghai Masters winner Hubert Hurkacz is also in the draw. He opens against Zhang Zhizhen on Wednesday
