Well, I'm going to back Jo here on this. The US Open is next so she needs to step up this week. And since it often seems to be a head game with her, I hope she has got her head as well as her game adjusted to the US hard courts now.
I think Jo has entered the Bronx next week which is a new tournament replacing New Haven. Not sure why Jo entered the Bronx in preference to San Jose unless it was a travelling issue. i.e having to go from the West Coast to East Coast.
1st set to Peterson very easily.
If she continues to serve as she has done this will be a 1st round exit for Jo who looks very poor, too many unforced errors and not enough decent serves. Starting to fear we may be witnessing another post Wimbledon melt down. Here's hoping for better in the next set.
