Maria Sharapova avoided an early exit from the Madrid Masters on Tuesday, rallying to beat Christina McHale to reach the third round.
Trailing 4-1 in the final set, Sharapova steadied her erratic service game and took command again to beat the 56th-ranked American 6-1, 4-6, 6-4 victory on clay at the Magic Box.
Earlier, Li Na continued her recent dominance of Zheng Jie by easing into the third round 6-2, 6-3 for her fourth straight victory against her fellow Chinese player. Zheng hasn't won a set from the second-ranked Li since her last victory in 2006.
Lucie Safarova of the Czech Republic also advanced with a 6-1, 6-2 win over Magdalena Rybarikova of Slovakia.
