Jack Sock wins as Sergiy Stakhovsky retires hurt in ATP Miami Men's 2nd round
Report after live commentary for Tennis TV as Jack Sock is through to face Milos Raonic in the 3rd round of the Miami ATP 1000 Masters tournament after Sergy Stakhovsky retired hurt. The American home favourite was already 6-2 3-2 up and with a break in the second set looked set to win comfortably regardless. Sock had raced into a 4-0 lead in the first set and dominated the match ever since. Stakhovsky is a natural serve-and-volley player but his movement looked inhibited from the start, with his troublesome lower crack eventually forcing him to retire early.
