Li Na has booked her spot in the second round of Wimbledon following a comfortable 6-1 6-1 victory over Michaella Krajicek on Tuesday.

Na took control of the match in the opening game of the first set as she broke the Krajicek serve, before holding to move 2-0 ahead.

Krajicek did manage to hold her next service game, but two successive breaks in the latter stages allowed Na to move into a one-set lead.

It proved to be just as straightforward for Na in the second as two quick breaks moved the 31-year-old into a 4-0 lead, eventually serving it out at 5-1 after just over an hour of tennis.
