Stephens 1.88, Giorgi 2.08
Head to heads are 1-1. They last met in July 2016 on a hard court in Canada. Giorgi won in 2 tie breaks. Stephens won in Cincinnati in 2012 on a hard court in straight sets.
Stephens still hasn’t won a match since she won the US Open In August. She did manage to win sets in the Federation Cup tie in November.

Giorgi won 60% of her matches in 2017. On hard courts that drops to 55%. She has come through the qualifying rounds this week but has never won a main draw match in Sydney.
Stephens does have stronger hard court results and I am going for her to win this. Wait for a price above 2.00 before entering. Fair chance of 3 sets.
Update: Superstar Stephens lost in straight sets.
