Auger-Aliassime advances in Chengdu with upset of second-seed Chung

Montreal’s Felix Auger-Aliassime picked up his second win over a top-25 player this season with a 7-6 (2), 5-7, 6-4 win over South Korea’s Hyeon Chung on Wednesday at the Chengdu Open.

The 18-year-old Auger-Aliassime, a lucky loser in Chengdu, had 11 aces and converted three of 10 break point opportunities against Chung, ranked 23rd in the world and seeded second at the Chinese tournament.

Auger-Aliassime will face Australia’s Bernard Tomic in the quarterfinals.

Auger-Aliassime is playing in his first tournament since retiring from his first-round match at the U.S. Open against fellow Canadian Denis Shapovalov with an accelerated heart rate.
