Mladenovic has made some improvements to her game over the past couple of months. I remember watching her back when she was trying to do a bad Lisicki impression, with glitchy technique. Big power, with no consistent rallying game, and not a whole lot in between the big winners and the big losers. What I always liked about her was that rocket first serve, and that she was strong enough to hit outright winners from behind the baseline. But I was beginning to think she'd just be a messy basher for the rest of her career
Nowadays, her rallying abilities are at an acceptable tour level, and despite the fact that her grip means that her FH will always be vulnerable against deep, flat shots, she's now able to change the direction of the ball much better off of both sides, to both open up the court and to deflect pace against the major hitters that she's been up against this week.
Her 1st serve remains a big weapon, and she is quite competent in the forecourt. Despite having a wonderfully athletic looking figure, she's slow and often a bit clumsy, which is a bit reminiscent of Vaidisova's issues. Her shot selection and match-play also seem to have improved significantly, which can probably be attributed to increased experience at tour level.
Overall, Mladenovic doing well is good for the game. A top French player would be a wonder right now for the WTA, and she's quite distinctive looking. In a good way, obviously.
Ludmila's current M.O of hitting 1 or 2
shots every 20 minutes and then about 30 homeruns in the meantime is going to see her out of the top 20 (even top 30), by the end of this year.
