Jack Sock has emerged as the top American junior. First All American final in junior US Open since Roddick and Ginepri in 2000. Jack Sock has got a very good consistent game, big serve. very competitive and fiery on the court, reallyu impressed by his demeanor and playing style. I see a very bright future for Jack Sock and expect him to turn pro after his senior year of high school this year.
