January 15, 2018: Roger Federer, the world No. 2, is the favourite to retain his Australian Open title over an injury - riddled field — Andy Murray and Kei Nishikori have already pulled out — when the first grand slam of the season starts in Melbourne on Monday. The world No. 1 and last year’s runner-up Rafael Nadal has a lingering injury scare and a seemingly tough draw. The women's field is wide open with defending champion Serena Williams pulling out, as she recovers from complications from her pregnancy.

Even before the first match, the Open courted at least two controversies — by allowing former champion Maria Sharapova (2009) to conduct the draw less than two years since she tested positive for a banned substance and former great Billy Jean King saying the Margaret Court Arena should be renamed because of the 11-time champion's "derogatory" views on sexuality.
