Monday morning's 4.7 magnitude earthquake near Anza—Southern California's biggest shaker in three years — rattled some of the world's top tennis players.
They're in Indian Wells — about 30 miles northeast of the epicenter — for the second week of the BNP Paribas Open.
Seven-time French Open winner Rafael Nadal, playing in his first hardcourt tournament in nearly a year, said this was the first earthquake he’d ever experienced.
“I was very scared,” Nadal told reporters today.
Nadal was getting ready for his third-round match against Argentina's Leonardo Mayer when the quake struck. He said it took him about a half second to realize what was going on.
“I was on the massage table preparing for my warm-up," said Nadal. “And I think the massage table moves even more.”
Nadal ended up getting a walkover, when Mayer withdrew from the tournament with a back injury. That put Nadal one match away from a quarterfinal clash with seven-time Wimbledon champ Roger Federer.
In a message on Facebook, Federer wrote that he felt the earthquake, and hoped everyone was OK.
Federer, Nadal and the rest of the tournament field should stay on their toes. The Anza are where today's earthquake struck is among the most seismically active regions in California.
