Jack Sock was once ranked as high as number 8 in the world in singles. But injuries caused him to completely drop out of the rankings at one point. Now, he is slowing moving up the rankings again.

Sock is also a fantastic doubles player. He has won three doubles grand slam titles and a mixed doubles grand slam title. He has two Olympic medals – a gold in mixed doubles and a bronze in doubles.

Sock has a big serve backed by an aggressive baseline game. His forehand and serve are his biggest weapons on the court. He has quick hands at the net, which helps to excel in doubles. 

His current sponsors are Lululemon and Babolat. He has earned over $11 million in his career.
