Muguruza has won both their previous matches. The most recent meeting was in September 2015. That was on a hard court and she won in straight sets. The other was in April last year on clay and she won that one in 2 sets.
Strycova beat Garcia in the 1st round. She might have been expecting more of a fight with Garcia but it was Vania King in the 2nd round who put her under more pressure. She still won in 2 sets.
Muguruza has reached the 4th round for the last 2 seasons. She has had 2 strong straight sets wins over Kontaveit and Flipkens. If Muguruza plays her normal game then she should be too strong but she is too low at 1.22.
I’ll wait to see if she gets broken before backing her.
