MELBOURNE, Jan 25 (Reuters) - Last ‌year's Australian Open runner-up, Alexander Zverev, stayed on track in his bid for an ‌elusive maiden Grand Slam title, beating Francisco Cerundolo 6-2 6-4 6-4 to reach the ‌quarter-finals at Melbourne Park on Sunday.

The 28-year-old German has lost all three Grand Slam title clashes he has contested, including last year's final to Jannik Sinner at Melbourne Park, and has flown under the radar this time as he ‍seeks another opportunity.
