There have been some changes in the coaching team for two young American men players.
Donald Young is now being coached by the USTA’s Mike Sell during the tour’s current swing through Asia. The 22 year old, who hit a low point after blasting at the USTA for not awarding him the French Open wild card, reached the fourth round of a major for the first time at the 2011 U.S. Open and is ranked a career high No. 55. He advanced to the second round of the Thailand Open on Tuesday when his opponent, Igor Andreev, retired in the second set.
Also, Amercian teenager Jack Sock, who recently turned pro and won the U.S. Open mixed doubles with Melanie Oudin, has rehired Mike Wolf as his coach after splitting with him prior to the U.S. Open. Sock will play USTA Challengers in Sacramento and Tiburon, California in the next two weeks.
