This is their first meeting.
Allertova was impressive in the win over Cetkovska although Cetkovska was as rusty as a 1980 Datsun. This year she has wins over Lisicki and Svitolina.
Kerber has only played one tournament since she won the Australian Open in January. She lost in the first round as a 1.19 favourite. She has lost her first match at Indian Wells for the past 2 years.
A Kerber win is by no means guaranteed. Winning a first Grand Slam can affect a player for months. Lay her around 1.20
