Bouchard won their only previous match. That was in March 2015 and she won in straight sets on a hard court.
Bouchard has her confidence back after a couple of poor seasons. She has beaten Cibulkova and Pavlyuchenkova in 2017.
Vandeweghe has a big serve so Bouchard will have to match her from the service line. Bouchard had a great record in slams until her form dropped in 2015. She was ranked 5th in 2014 and if she can find that sort of form she will take this.
Vandeweghe has beaten Vinci so far this year and struggled a little against Parmentier in the last round.
Back Bouchard if she is broken first.
Update: Vandweghe won in 3 sets. Bouchard was a break ahead in set 3.
