Other local interest
Kiwi double pairing Rosie Cheng and Katherine Westbury are also in action, facing Petra Martic (Croatia) and Anna Tatishvili (USA). They will be rank outsiders, though 16-year-old Cheng impressed in her singles qualifying match, which was her debut at this level.
Don't forget the outside courts
Aside from the centre court battles, there are some great matches in prospect on the outside courts. 2014 ASB Classic semi-finalist Kirsten Flipkens against Swede Johanna Larsson should be an enthralling contest, while American Coco Vandeweghe's match with Roberta Vinci could be one of the games of the day.
Courting controversy?
It will be interesting if there is any reaction to Glushko's presence tomorrow on centre court.
The appearance of Israeli players at the tournament has caused a stir in the past, with vocal protests against Shahar Peer outside the arena in 2009.
Stat of the day
Croatian wild card Ana Konjuh, who was so impressive last night in a straight sets win over eighth seed Mona Barthel, is the youngest player in the tournament. Konjuh celebrated her 17th birthday two weeks ago while 34-year-old Williams is the senior player in the main draw.
