Auger-Aliassime outguns Tsitsipas at Indian Wells
Felix Auger-Aliassime won the battle of the young guns by beating ninth seed Stefanos Tsitsipas 6-4 6-2 on Saturday to advance to the BNP Paribas Open third round.
The 18-year-old Canadian, the youngest player in the world top 100, fired an unreturnable serve on match point to defeat the 20-year-old Tsitsipas - who is the youngest player in the top 10.
While the outcome is an upset on paper, Auger-Aliassime held a 3-0 advantage over Tsitsipas when they met as juniors.
Next up for last month's Rio Open finalist is either Japan's Yoshihito Nishioka or Spain's Roberto Bautista Agut, who play their second-round match later on Saturday.
