Melbourne: Rafael Nadal says he is driven to restore his slumping ranking after powering past Germany's Florian Mayer into the second round of the Australian Open yesterday. The long-time World No. 1 looked back to his healthy best after an injury-riddled 2016 as he tossed the 49th-ranked Mayer 6-3, 6-4, 6-4 in just over two hours on Rod Laver Arena.
