Nishikori upsets Tsonga

Kei Nishikori came from a set down to become the first Japanese man to advance to the quarter-finals of the Australian Open in 80 years on Monday when he upset sixth seed Jo-Wilfried Tsonga 2-6 6-2 6-1 3-6 6-3. Tsonga was ultimately plagued by errros, which Nishikori took full advantage of matching Tsonga stroke for stroke and waited until the Frenchman got impatient and made an unforced error. Despite hints of Tsonga's brilliant play, it wasn't enough to beat the Japanese wonderkid and is an early exit for the man who people had much faith in to disrupt the world order of the Top 4 men in tennis. The 24th-seeded Nishikori, who has now matched the feats of Ryosuki Nunoi and Jiro Satoh when they made the last eight in Australia in 1932, will meet fourth-seeded Briton Andy Murray in the quarter-finals.
