Sixth-seeded Alexander Zverev hit 15 aces on his way to the third round at the French Open.
He got there by beating a familiar face. Zverev and Roman Safiullin have known each other since they were 4 years old.
The Russian qualifier put up a good fight, but Zverev went for his shots when it mattered and prevailed in straight sets.
He won 7-6 (4), 6-3, 7-6 (1) on Court Suzanne Lenglen.
Zverev had been pushed to five sets in the previous round against another qualifier.
