Melbourne: World number one Angelique Kerber battled past Lesia Tsurenko to get her first Grand Slam title defence off to a stuttering start at the Australian Open Monday.
The top seed ultimately proved too much for the Ukrainian, winning 6-2, 5-7, 6-2 on Rod Laver Arena, but the laboured victory was less than impressive from the German.
