The scariest moment of Rafael Nadal's day didn't happen on the tennis court.
The Spaniard experienced his first earthquake Monday morning at the BNP Paribas Open. The 9:55 a.m. quake had an estimated magnitude of 4.7, according to the California Institute of Technology's seismological laboratory.
The epicenter was about 12 miles from the desert community of Anza, which is near Indian Wells, site of the combined men's and women's tennis tournament.
Nadal was on the massage table preparing for his third-round match against Leonardo Mayer of Argentina.
Nadal says he was "very scared" and he thinks the table moved more during the quake than if he had been standing or sitting. He says his legs were wobbling.
After the excitement caused by the quake, Nadal didn't even get to play his match. Mayer withdrew because of a back injury.
