Second set: Barty* 6-1 1-1 Hercog (*denotes server): Better again from Hercog, who remains happy to engage Barty in baseline rallies before working the expanses of the court. She succeeds in making Barty run, taking the Australian’s serve to deuce, but Barty is too good for this tactic to work all the time. An unforced error from Hercog, followed by a Barty ace, means the world No 1 holds all the same. 2.42am GMT
Second set: Barty 6-1 0-1 Hercog* (*denotes server): Hercog manages deeper penetration with her first serve - and manages to get some of them in - and she holds in her best service game of the match. The Slovenian had been off for almost four months prior to this tournament, so perhaps she might be warming to her task.
