Ivo Karlovic sets world serve record
ZAGREB, Croatia -- The International Tennis Federation confirmed Sunday that Ivo Karlovic of Croatia broke the world record for the fastest serve.
He struck a 156 mph serve in the fourth set of a doubles match against Germany in the Davis Cup on Saturday, breaking Andy Roddick's previous record of 155 mph.
"I noticed that while serving, saw it on the screen," said the 6-foot-10 Karlovic, the tallest player on the ATP circuit. "It is really great."
Roddick also blasted his serve in the Davis Cup, against Vladimir Voltchkov and Belarus in 2004.
