FIVE THINGS TO WATCH IN ACAPULCO
1) Medvedev Leads The Field: Medvedev came within one set of capturing his second Grand Slam title at the Australian Open in January, falling to Rafael Nadal in a five-set classic. The Russian returns to court for the first time since at the Abierto Mexicano Telcel presentado por HSBC, where he will make his debut. The World No. 2 will open against Benoit Paire.
It is a critical week for Medvedev, who controls his destiny in the battle for the No. 1 ATP Ranking with Djokovic. If the Russian lifts the trophy in Acapulco, he will become the third Russian to accomplish the feat by climbing to the top spot on 28 February. Learn all the No. 1 scenarios here.
2) Defending Champion Zverev: Alexander Zverev has fond memories in Acapulco, having triumphed in Mexico last year. The German, who did not drop a set en route to the title, reached the final in Montpellier earlier this month. The World No. 3 will face American Jenson Brooksby in a promising first-round match.
At last year's BNP Paribas Open at Indian Wells, Zverev needed three sets to dispatch the American. This will be their second ATP Head2Head clash.
