Juan Martin del Potro reaches Rotterdam Open final

Juan Martin del Potro has reached a second consecutive Rotterdam Open final with a straight-sets victory over Grigor Dimitrov.

The Argentine world number seven took 75 minutes to beat his Bulgarian opponent 6-4 6-4.

"I'm glad I was able to beat him, he's a newcomer with a lot of potential," said Del Potro.

"I used my serve well today. I've improved my game since the quarter-finals, but if I want to win the title I have to get that little bit better."

Del Potro, who will face either Julien Benneteau or Gilles Simon on Sunday, lost out in last year's final to Roger Federer.
