Janko Tipsarevic has booked his place in the fourth round of the Miami Masters thanks to a three-set win against Kevin Anderson.

Anderson clinched the first set 6-4 before seventh seed Tipsarevic levelled the match by taking the second 7-5 in the tie-break.

Play was halted at the start of the third when the Serbian called for medical assistance on a leg injury.

However, he came back out after the interval to brush his South African opponent aside 6-0.

Tipsarevic will now take on 11th seed Gilles Simon with a quarter-final spot awaiting the winner.
