The first time Jason Holmes was approached about an AFL career, the former US college basketballer noted the date.
"I had no clue what it was," he said.
"I think I'd seen it in Funny People and on ESPN2.
"But I hadn't realised what it was at the time.
"I literally got the call on April 1, so I thought it was a joke."
But the emails and messages kept coming, so Holmes figured he had better pay more serious attention.
Less than three years after switching to the sport, the 25-year-old St Kilda ruckman will make his senior debut on Saturday night against Geelong.
Holmes is the first American born-and-raised player.
Sanford Wheeler also played for the Sydney Swans from 1989-94, but he moved to Australia when he was five.
Holmes had to start from scratch in his 20s.
"It's one of the dreams they sell us when they try to get Americans over here," Holmes said of his trailblazing.
"I don't think it's sunk in yet and I understand it's a really big thing.
"But I'm just proud to be a cog in the machine that's going to help this sport grow internationally."
