Andrey Rublev, 19, continued his magnificent US Open run with a 7-5, 7-6, 6-3 victory over No. 9 David Goffin to become the youngest quarterfinalist in Flushing Meadows since Andy Roddick in 2001. Here's a quick primer on the teenage sensation:
- The young Russian, who won the 2014 French Open boys' singles title, learned tennis from his mother, Marina Marenko.
- Rublev won his first tour-level title in Umag this year, earning entry into the main draw as a lucky loser.
- After the 2014 US Open, Rublev was invited to train with his next opponent, No. 1 Rafael Nadal, for a week in Mallorca.
- The 19-year-old's first Grand Slam main-draw appearance was at the 2015 US Open, when he qualified before losing to fellow 2017 quarterfinalist Kevin Anderson in four sets.
- Andrey Rublev Sr., the quarterfinalist's father, is a restaurateur and was once a professional boxer.
