Medvedev ousted by Cerundolo at Miami Open
Medvedev, who reached the final at Indian Wells earlier this month, looked to be heading for a brisk exit after 18th seed Cerundolo raced through the first set in just over 20 minutes.
But Medvedev rallied in the second set to level the match, and there was little to choose between the two in the deciding set.
