Re: Wuhan 1R: [Q] Lepchenko def.  Keys 62 76(4)
Madison had two set points in the second set. Her way to warm up to the Asian tour probably (just kidding).
Varvara isn't an easy opponent. Can stand power, has a vicious and deep forehand, and can keep a ball in the court, and is a lefty. Madison isn't secure enough about her shots. She's been told that a lot already, but she just struggles to keep a ball in the court for not being patient enough. Of course, being patient also could expose her to just being blown off the court in two sets by a player like Lepchenko. So for her it's a difficulty to find the right mix. That's where she improved this year (and slowly - very slowly - over the years): find the right mix while still winning with her flat hitting style. But when she doesn't have the rhythm, the feels, the accurate footwork, etc, it's a mess of UEs.
It's been suggested that she uses more topspin to be more consistent in rallies, but I'm not sure it would work. Each player is different. Madison doesn't play like Sloane, either Venus like Serena.
Madison can play more smart, but with her own game. That's the work to do.
