Jo-Wilfried Tsonga into 3rd round

— -- MELBOURNE, Australia -- Jo-Wilfried Tsonga started his match under the blazing sun and finished it with a roof over the court while beating Thomaz Bellucci 7-6 (6), 6-4, 6-4 on Thursday during a chaotic day of searing temperatures at the Australian Open.

The tournament's extreme heat policy was put into effect during the match when the temperature exceeded 108 degrees, meaning a brief delay while the roof at Hisense Arena was closed following the completion of the first set.

Tsonga defeated Andy Murray and Rafael Nadal at Melbourne Park in 2008 en route to the final, where he lost to Novak Djokovic.

Last year, Tsonga lost in the quarterfinals in five sets to Roger Federer.

Earlier, Kei Nishikori advanced to the third round, starting and finishing quickly in a 6-1, 6-1, 7-6 (3) win over Dusan Lajovic of Serbia.

The 16th-seeded Nishikori, who won the warm-up exhibition tournament at Kooyong last week in Melbourne and then endured a five-set first-round win here, will play either Andreas Seppi or Donald Young of the United States on Saturday.

Nishikori's match finished in temperatures of 106 Fahrenheit, several degrees lower than the forecast high of 111 expected later Thursday.
