No.1 seed Serena Williams holds a 3-0 head-to-head lead across all three surfaces over compatriot Christina McHale - but none of those wins, all in 2016 as the World No.1, came easily. In the second round of Miami, Williams led 6-3, 5-3 and held a match point before McHale forced a third set, with Williams eventually winning 6-3, 5-7, 6-2 in two hours and eight minutes; in the third round of Rome, she needed to save a set point before pulling away 7-6(7), 6-1; and in the second round of Wimbledon, she would miss a set point in the first set and need to come from 0-2 down in the decider before triumphing 6-7(7), 6-2, 6-4 in two hours and 35 minutes. However, after surviving McHale, Williams would go on to lift both the Rome and Wimbledon trophies.

Coco Gauff could face Williams in a popcorn quarterfinal if both win their matches today. The 15-year-old Gauff will be taking on Laura Siegemund for the first time, and is bidding to reach the last eight of a WTA event for the second time following her Linz title in October. This week, Gauff is ranked at a career high of World No.67 while Siegemund is at World No.73, making this just the second time that the American teenager has faced a lower-ranked opponent in a WTA main draw (following her win over Stefanie Voegele in the first round of Linz).

2015 and 2018 runner-up Caroline Wozniacki takes on 2017 champion Lauren Davis for the third time today. No.5 seed Wozniacki is yet to drop a set to the American, having won 7-5, 6-1 in the 2017 Doha quarterfinals and 6-1, 6-3 in the first round of Beijing last year.

Two-time defending champion Julia Goerges is one of only three players to have won consecutive Auckland titles, along with 1988-89 champion Patty Fendick and 2003-04 winner Eleni Daniilidou. The German will bid for her sixth consecutive quarterfinal today in her first meeting with Prague and Palermo champion Jil Teichmann.
