MELBOURNE, Australia — When faced with adversity in her first competitive match in 15 months, Bianca Andreescu recalled how she persevered in some of her big victories in her breakout 2019 season. It helped the Canadian overcome a stiff challenge in a 6-2, 4-6, 6-3 first-round win over Romania's Mihaela Buzarnescu on Monday at the Australian Open. Serving at 3-3 in the deciding set and down love-40, Andreescu reeled off five straight points for the hold and took control of the match from there. "I have a little bit of a feel of how it is to be in that situation," she said.
