Grigor Dimitrov battles past Fabio Fognini in Madrid

Grigor Dimitrov has seen off Fabio Fognini in three sets to reach the Madrid Open third round.

The 10th seed will now face Stanislas Wawrinka for a spot in the quarter-finals of the tournament.

Fognini opened up a 3-0 lead at the start of the opening set, and the volatile Italian was able to keep Dimitrov at arm's length after that to take it 6-3.

An unpredictable second set saw Dimitrov squander two break points before saving five more on his own serve. The Bulgarian then broke twice on his way to winning 6-2.

Dimitrov let a 3-0 lead in the decider slip from his grasp as Fognini mounted a comeback, but the former Wimbledon semi-finalist eventually ground his opponent down to seal his progress 3-6 6-2 7-5.
