(AP) -- 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 Canadian Open while in front after his wife went into labor.
He tweeted: ``What a whirlwind of a day.'' He says Zoe Olivia Mahan was born at 3:26 a.m. in Texas.
Mahan was leading the tournament in Oakville, Ontario, after two rounds Saturday. He flew home to Dallas when his wife went into labor a month before her due date.
He says in another tweet 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 would have been on the course at Glen Abbey Golf Club for the third round when his wife began having labor pains, but his tee time was delayed 80 minutes by a thunderstorm.
