(Reuters) - World number two Jason Day has pulled out of next week's World Golf Championships (WGC) event in Mexico City due to illness, the Australian announced on Sunday.

"I have a double ear infection and the flu, which precludes me from preparing for and playing in the tournament," he said in a statement.
