Medvedev clinches semifinal spot in Acapulco, assured of World No.1 ranking
The World No.2 brushed past his Japanese opponent in a thrilling 6-2 6-3 victory, winning 70% of points behind his first serve. The top seed broke Nishioka's serve on six occasions, winning four straight games to close out the first set.
Nishioka established a 3-1 lead in the second set, but Medvedev rallied to win the next five games and clinch victory after an hour and 10 minutes.
Making his debut in Acapulco, the Russian improves to 12-2 on the season and does his part to set up a blockbuster semi-final against Rafael Nadal — a rematch of their five-set Australian Open final. The Spaniard faces Tommy Paul on Thursday night.
