Head to heads are 1-1. The most recent was in January this year. Konta won in straight sets on a hard court.
Stats for 2016 are very similar.
Konta was too strong for Brengle in the last round. She faced just 1 break point which she saved.
Allertova has wins over Lisicki and Svitolina this year but apart from those 2 wins she has fallen to higher ranked players.
I think Konta will trade higher than her 1.58 starting price but that she will come through in the end. Wait for 1.80 on her.
