Lightning did strike twice at the French Open on Tuesday.
One year almost to the day that Robin Soderling stunned the tennis world by becoming the first man to defeat Rafael Nadal at Roland Garros, the Swede fired another bolt of electricity as he downed the great Roger Federer.
His 3-6, 6-3, 7-5, 6-4 win meant that for the second straight year he had beaten the world number one and defending champion in Paris and now he moves on to a semi-final against Tomas Berdych of the Czech Republic on Friday.
How do the two huge wins compare? Soderling has no ready answer.
"It's a tough question," he said.
"I think they're both big wins, of course. They were both No. 1s. They're different players, and I'm really happy that I showed that I can beat them both.
"But again, I don't think about it that much. Of course I lost a lot of times (12 times to Federer), so it's a great feeling to finally end that streak.
