Argentina's Juan Martin del Potro advanced to the final of the ABN AMRO World Tennis Tournament in Rotterdam by defeating Bulgaria's Grigor Dmitrov 6-4, 6-4 on Saturday.
Del Potro dominated his service games for the most part, while one break of Dimitrov's serve in each set gave him the margin of victory.
"The match was tough," The Argentine world No. 7 said in the post-match press conference. "The breaks I got gave me the confidence to be aggressive all the time and play my game throughout the match."
"I think I'm serving really well, but I feel like I can improve a little bit for tomorrow. I faced break points today, so that means I need to improve if I want to win" on Sunday.
The 41st-ranked Dmitrov, who has been touted as a potential top-10 player for years and will climb higher in rankings thanks to this week's result, said he was pleased to reach the semifinals of this Netherlands indoor hard-court event.
"Juan Martin is one of the toughest guys to play on tour. He played very good tennis today; he deserved to win the match. It's always nice to get through a couple of tough matches," the 21-year-old said.
Next up for Del Potro on Sunday will be the winner of the all-French second semifinal pitting Julien Benneteau, who stunned top seed Roger Federer on Friday, against Gilles Simon.
Del Potro also reached the Rotterdam final last year but lost to Federer in straight sets. EFE
