- Andrea Petkovic suffered an injury scare early in her first round match against Julia Goerges. Petkovic came down awkwardly after an overhead smash during the warm-up and told WTA Insider she felt her knee buckle. After getting it taped in the second game of the match, Petkovic said she continued to feel pain until the pain-killers kicked in, beating Goerges, 6-4, 6-2. She will see a doctor to find out the extent of the injury.
- Madison Keys got some revenge over No.12 seed Timea Bacsinszky, avenging her French Open loss with a 6-4, 6-3 win in the first round of Cincinnati on Monday. More on Keys' big win via the Cincinnati Enquirer.
- Keys told reporters the reason for her withdrawal from last week's Rogers Cup was to deal with a left wrist injury. Keys, who has been hampered by ill-timed injuries at Slams in the past, chose to address the injury early as opposed to risk her chances at the US Open.
"It's never an easy thing to pull out of a tournament. You always want to play. But I think there has been so many cases where I've gotten hurt at a Grand Slam. Pulling out of Wimbledon because I was hurt was the worst thing. For me, learning from experience and not pushing myself to the point of completely breaking down is the smarter choice."
- The final US Open wildcards have been announced: Louisa Chirico, Samantha Crawford, Nicole Gibbs, Sachia Vickery, Jamie Loeb, Bethanie Mattek-Sands, Sofia Kenin, and Océane Dodin have received wildcards into the main draw. Vicky Duval, Robin Anderson, Usue Arconada, Tornado Alicia Black, Claire Liu, Raveena Kingsley, Jessica Pegula, and Bernarda Pera have received wildcards into qualifying.
- Petra Kvitova has upped her practice level this week in Cincinnati, in response to feeling underprepared with a limited practice schedule in Toronto.
"When we found out about the mono we cut almost everything. I was practicing just an hour in the morning and 30 minutes of fitness in the afternoon. Be more kind of relaxed. When I saw how I was playing against Vika that I really didn't have [enough] time on court. This time I practiced one hour in the morning and an hour in the afternoon. I hope I will be fine. I never know. Sometimes I wake up in the morning and I feel good. The other day I felt a little bit tired and sleepy. It's a little bit up and down. I never know."
