NEW YORK (Reuters) - Bianca Andreescu overcame stomach pain and a stiff challenge from Viktorija Golubic to advance 7-5 4-6 7-5 into the second round of the U.S. Open on Tuesday.

The 21-year-old, making her return to Arthur Ashe Stadium for the first time since she won the tournament in 2019, got all she could handle from the Swiss in the nearly three-hour affair on a hot and humid night in New York.
