Assuming Laura avoids injuries etc., I see her having a solid senior career as a bare minimum. Top 50 and then lets see how much higher she can go, lack of speed will always hold her back somewhat, so some observers are undoubtably going to be disappointed if she doesn't win a slam.
The current crop of juniors doesn't contain a multi grand slammer so it is possible Laura is looking good compared to an average bunch of players.
Her match tonight according to oldechoman is going to be delayed about 10 minutes.
