VIDEO - Highlights: Nishikori videre Australian Open efter dramatisk tiebreak

Kei Nishikori tabte de første to sæt, men fik kæmpet sig videre efter fem meget dramatiske sæt mod spanske Pablo Carreno-Busta.

January sees the tennis season blaze into life on the scorching hard courts of Melbourne Park. The first Grand Slam of 2019 sees world number one Novak Djokovic aiming for his third consecutive slam title, and seventh Australian Open. He faces tough opposition from defending champion Roger Federer, while Rafa Nadal aims for his first triumph Down Under since 2009. Andy Murray hopes to go far as he steps up his comeback from injury, while controversial home favourite Nick Kyrgios is bound to attract attention - good or bad.

On the women's side, all eyes will be on Serena Williams as she aims for Grand Slam number 24. Among those looking to halt Serena's charge: world number one Simona Halep, defending champion Caroline Wozniacki and US Open winner Naomi Osaka.
