Kei Nishikori makes light work of Mikhail Youzhny in Miami

Fourth seed Kei Nishikori cruised into the third round of the Miami Masters by losing just three games in a straight-sets win over Mikhail Youzhny this afternoon.

Russia's Youzhny saved an early break point for Nishikori in the first game, but was soon broken as the favourite won three games in a row to grab a 3-1 advantage.

He broke once more in the first set on his way to a 6-2 triumph in just half an hour.

World number 64 Youzhny was in trouble right from the off in the second set as Nishikori broke in the opening game before going on to wrap up victory 6-1 in just over an hour.

Nishikori, who didn't offer Youzhny a single break point in the match, will face either 32nd seed Victor Troicki or Italy's Simone Bolelli in the next round.
