Couldn't believe I watched this match all the way. Peng was leading 5-1 in the second set and blew that lead and lost it in a tie breaker, then had a 4-1 lead and blew that lead to barely squeak out a win in another tie breaker.
I'm going to be a little harsh on Peng because she did what she was supposed to do in the first set and the 5-1 lead in the second set. She moved Keys around and forced a lot of errors from her with her poor foot work from Keys. After she got that 5-1 lead, Peng just sat on that lead and played like she was a back board and returned shots directly back at Keys, who then pounded balls back at Peng which frequently resulted in short balls that Keys would get winners from. In the third set Peng again moved Keys around and got it to a 4-1 lead and then Peng decided to turn her brain off and just played retrieval role and Keys again pounded the ball back at Peng. Keys really should of won this match if she didn't make several bad errors on easy hits into the net in the tie breaker, she looked the much stronger player at that point. All Peng wanted to do was retrieve and hope for errors.
As for Keys... I can see Keys getting into the top 20 with her power and serving. But her poor movement, poor footwork especially when she gets moved to her backhand side combined with her weak backhand are major flaws to Keys game at the moment. Keys is young, hopefully she can get a trainer to help her on her court coverage which is an issue since she can be pulled side to side very easily. As to her foot work problems, she is just going to need to buckle down and work on that every moment she can. The reason why she gets so many errors on her backhand side is because she can't get her feet set for those returns. She shanks a lot of backhands long or into the net.
Not sure you can say this was a great win for Peng, but at least she is through. Some serious mental lapses on her part in this match.
