Tennis-Medvedev dominates Andujar to reach last eight in Acapulco

Daniil Medvedev crushed Pablo Andujar 6-1 6-2 in Acapulco on Wednesday and put himself three wins away from victory at the tournament and rising to world number one for the first time.

Top-seeded Medvedev pretended like he might serve underhand on match point but instead thumped his seventh ace, eliciting a smile from the Spaniard who played well but who could not break down the Russian's firm defense.

Medvedev will next face either American Taylor Fritz or Japan's Yoshihito Nishioka as he looks to wrest the world number one ranking from Novak Djokovic.
