Del Potro faces Berdych in Madrid semis
Tomas Berdych needed a little more than an hour to beat Fernando Verdasco 6-1, 6-2 in the quarterfinals of the 2012 Madrid Masters.
Berdych will meet Juan Martin del Potro in the semi-finals after the Argentine defeated Alexandr Dolgopolov 6-3, 6-4 .
Berdych has yet to be broken in 25 service games this week. He lost just nine of his service points and hit four aces past Verdasco for his 25th match win of the season.
"I feel great," said Berdych. "I'm in another semi-final, [the] second in a row. To beat Fernando made me feel great. It is always tough to beat Fernando, even though the score looks quite easy. It's not easy to beat a Top 20 player and he played great yesterday [against Rafael Nadal]."
On playing del Potro, Berdych said, "I'm expecting a really tough match. To play Juan Martin is always tough, he's a great guy and he knows how to win the Grand Slams. He's definitely back after his [wrist] injury. So far this year, I have already lost to him and it would be nice to get him back now. I will try to do my best, to play my game, to be aggressive."
Del Potro maintained his run of form on clay and claimed the win in 84 minutes. He hit 10 aces, won 69 per cent of his service points and converted three of his seven break point opportunities.
