Back in March, we told you the story of a Canadian teenager who was making some waves in the tennis scene. If you weren't a tennis fan—or a sports fan—you might have skipped that episode. But since then something's happened. Or more accurately, something hasn't happen: Andreescu hasn't lost a completed match since early March. She won her first title two days after we recorded this episode, then missed nine weeks with a shoulder injury and is undefeated since her return, taking home the Rogers Cup title in Toronto in the process. Now that she's through to the quarter-finals of the US Open in New York, we thought we'd give you a chance to catch up if you haven't already—and meet the new face of Canadian sporting dominance.
