(Reuters) – Reilly Opelka fired off 11 aces in a 7-5 6-3 win over Japan’s Taro Daniel as he advanced to the third round of Indian Wells on Saturday.
The 24-year-old American, who enjoyed his best Grand Slam showing last month when he reached the fourth round of the U.S. Open, won more than 90% of his first-serve points and never faced a break point as he made light work of Daniel.
Polish eighth seed Hubert Hurkacz broke down the stubborn resistance of Alexei Popyrin to secure a 6-1 7-5 win.
Australian Ajla Tomljanovic secured the sole upset of the early matches, recovering from a rocky second set to send fifth seed Garbine Muguruza packing 6-3 1-6 6-3.
“I was really looking forward to playing Garbine because I did lose last couple of times but I did try to focus on that one time I beat her and channel that energy, so I was really happy I got through today,” Tomljanovic said in a post-match interview.
Newly minted U.S. Open champion Daniil Medvedev will be in action later on Saturday against Mackenzie McDonald, while defending women’s champion Bianca Andreescu will play American Alison Riske.
