Hunter Mahan has made the happy jump from tournament leader to proud father.
He announced the birth of his daughter Sunday, a day after he withdrew from the RBC Canadian Open while leading after his wife went into labor.
"What a whirlwind of a day," he tweeted on Sunday, after Zoe Olivia Mahan was born at 3:26 a.m. in Dallas.
He said in another tweet that his wife and daughter are "doing great." He thanked his sponsors for appreciating "what's important in life" and saluted his fans for "being Awesome!"
Mahan was leading the tournament after 36 holes and was preparing to tee off in the third round when he got the news that his wife had gone into labor about a month before her expected due date. He would have already been out on the course when his wife began having labor pains, but his tee time was delayed 80 minutes by a thunderstorm.
