Erica’s pregnancy was one of the best kept secrets in the golf world this year. Speaking after the news emerged Rory said: "I didn't think it was something that I really particularly needed to share out there.
It's a private matter, but we're really excited and can't wait for her to get here." McIlroy announced the birth via social media and thanked the staff at the Jupiter Medical Center in Florida and described his daughter as "the absolute love of our lives.
Mother and baby are doing great." McIlroy revealed during the BMW Championship that he had "been waiting for the call" due to the imminent birth, and Poppy Kennedy McIlroy arrived at lunchtime on Monday. McIlroy and wife Erica had managed to keep the news of the pregnancy under wraps until last week when it was announced on The Golf Channel's live broadcast of the BMW Championship on Friday evening.
The 31-year-old and his caddie Harry Diamond - also a long-term friend - were ready to take the call on the course should Erica’s waters break. Following his third round at Olympia Fields on Saturday, when news of his wife's pregnancy was first made public, McIlroy hinted that he could miss the PGA Tour's season finale.
"Definitely, just depending on what happens," he said when asked about the prospect of staying at home this week. "I'm going to play in many more Tour Championships and it's only going to be the birth of your first child once.
That trumps anything else."
Luckily he was on hand to be by her side, as Erica welcomed little Poppy into the world.
McIlroy and Stoll married in 2017 at a castle that was built in the 13th century located in Cong, Ireland.
The two met through the game of golf — Stoll was working for the PGA Tour when the two connected. The world No 4 is expected to play in this week's Tour Championship in Atlanta, which starts on Friday, although he did cancel his pre-tournament press conference.
He is scheduled to play alongside Brendon Todd in Friday's first round at East Lake, with both starting the tournament on three under par - seven behind FedExCup leader Dustin Johnson.
