Miami Open: Azarenka retires, Muchova moves into third round

No 15 seed Karolina Muchova advanced to the third round of the Miami Open when Belarusian Victoria Azarenka (photo) retired at the Hard Rock Stadium on Friday evening.

Muchova, ranked No 14, led 6-0, 0-0 when Azarenka, ranked No 32, pulled out, for what looks like an injury to the left shoulder.

Karolina Muchova will play the winner of the match between Swiss Belinda Bencic and Ukrainian Elina Svitolina, the No 22 seed, next.
