Sam Stosur is through to the last 16 at Indian Wells after a 6-4, 2-6, 6-4 win over American Christina McHale.

Stosur fell behind 3-0 in the deciding set, before rallying, to win six of the next seven games to advance.

The Australian 26th seed will likely face two-time Australian Open champion champion Victoria Azarenka for a place in the quarter finals.
