Madrid - World number two Li Na secured her place in the third round of the Madrid Open on Tuesday with a comfortable 6-2, 6-3 win over compatriot Zheng Jie.

Zheng led the head-to-head record between the two 4-3 before the match, but Li has now won the last four meetings between the pair in straight sets and will face 16th seed Sloane Stephens or Petra Cetkovska in the last 16.
