Tommy Haas has promised to cherish his surprise run at the Miami Masters following his semi-final defeat to David Ferrer.

The 34-year-old German defeated world number one Novak Djokovic and 11th seed Gilles Simon on his way to the last four of the tournament in Florida.

However, he was unable to get past third seed Ferrer on Friday as the Spaniard claimed a 4-6 6-2 6-3 win.

"Anytime you lose it's tough, but beating Novak Djokovic, coming back, beating Simon, getting to the semis — it's been an unbelievable tournament, something that I will definitely cherish for the rest of my life," Haas told reporters.

"I will try to continue as long as I can, because this is a lot of fun. In the end of the day, the most joyful time I have is when I'm on the court playing great tennis, entertaining the crowd, playing in front of the big, on the big stadiums."

Haas is currently into the 13th year of his professional career, winning 13 ATP singles titles during that time.
