What do you think Caro should do then? Change/modify the style she's trying to play now?
I don't know. I am not a tennis coach. I don't know what they are telling her/practicing with her. She can't defend as well as she used to, something that is very evident in this match where she was mostly on defence all match. But her game is not imposing enough to play this aggressive brand of tennis she's trying to play, none of the top aggressive players would get dictated to like Wozniacki did tonight by Halep.
Look aggression is good, but you have to question the improvements (or lack of them) in certain areas. She's trying to come forward more often, anytime someone makes her hit a forehand volley she's in trouble, she bricks nearly every one. Coaches, other players will soon pick up on this and make her hit more forehand volleys. Same problem putting away short forehands, overheads. These are mainly simple things, these all existed when she was world number 1 too, but back then she was a lot better at defending. Now she gets in too many of these exchanges where she's running side to side, and her ball just isn't threatening enough.
I also think at times she hasn't found the balance of knowing when to attack, she attacks on some of the wrong balls, some of the wrong times.
In theory Caro's first 3 rounds next week look really easy. I have never seen Ying-Ying Duan play though. Caro won't have a better chance than this to make the semi-finals, almost anything less than a semi final in this draw is a disappointment. That sounds big expectations, but I really think Caro will be disappointed if she loses to anyone in this quarter. I don't know what to expect yet though, you have to see the form of some of these players next week.
