Nadal wins on day of heat-related turmoil

ON A day when the Australian Open schedule was significantly disrupted by the heatwave bakingVictoria, world No.1 Rafael Nadal applied the blowtorch to young Aussie Thanasi Kokkinakis.

To his credit, the 17-year-old wildcard was far from overawed. Showing his full range of shots, Kokkinakis took the match up to the Spaniard (pictured) before losing 6-2 6-4 6-2

That match was one of just a handful in the men's singles draw that were completed on a day when the temperature reached 44 degrees.

Once it passed 40 just after midday, officials invoked the extreme heat policy and suspended play on all outside courts for about six hours.

Tournament director Craig Tiley said he hoped a cool change expected to hit the Victorian capital later today and drop maximum temperatures by about 20 degrees for several days, would enable the schedule to return to normal.

Once play did resume, Aussies Ashleigh Barty and Casey Dellacqua took just 52 minutes to beat Czech pair Alexandra Panova and Kristina Pliskova 6-1 6-1 to move into the second round of the doubles.
