GEELONG superstar Patrick Dangerfield has formally announced the birth of his first child, George Patrick Dangerfield, via his fishing podcast.

Dangerfield said that while he always said the baby's gender wouldn't matter, he couldn't hide his excitement when he found out on Tuesday night that it was a boy.

"When I saw that little willy, I could have done cartwheels in that room," he said on his fishing podcast Reel Adventures.

The pressure is already mounting on the golden child, with Adelaide and Geelong fans licking their lips at the prospect of a future father-son selection.

The Crows lead the race after the Brownlow medallist played 154 games for Adelaide, but Cats fans still have hope as he continues to add to his 38 games at the Cattery.

The keen fisherman said his wife Mardi was healthy, and joked that the boy had reached regulation size.

"(He is) weighing in at seven pounds, 12 ounces, and just over the half-metre mark, so we'll be keeping him."

Dangerfield is now certain to play for Geelong in its clash with the Brisbane Lions on Saturday night.
