Top seed Rafael Nadal gave Australian teenager Thanasi Kokkinakis a good tennis lesson by dismantling the wild card 6-2, 6-4, 6-2 to reach the men’s singles third round at the Australian Open here Thursday.

The 17-year-old Kokkinakis blazed 21 winners against the World No. 1 but his potential was still not enough to match the super-fit Spaniard who wrapped up the match within two hours. IANS
