Jason Day and his wife, Ellie, welcomed their first child into the world early on Wednesday, according to the Australian Associated Press. Dash James Day was born weighing 8 pounds, 4 ounces.
The 24-year-old said in February he didn't want to be an "old dad."
"I'm a little nervous, obviously, being a father for the first time," he said. "I'm also excited at the same time. I've always wanted to have kids. I love kids."
It is unclear if Day will make the trip to Royal Lytham and St. Annes for next week's British Open.
