Career
Previously a professional baseball outfielder who played for the Australian national baseball team and in the San Diego Padres minor league system, he retired from baseball in 2014 to pursue an Australian rules football career, signing with the West Coast Eagles in the Australian Football League (American Federation of Labor-Congress). He was signed to West Coast"s rookie list under the three-year non-registered rule, which allows clubs to recruit players who have not been registered with an American Federation of Labor-Congress-affiliated competition for more than three years. Adamson began the 2015 season in the WAFL reserves, playing for West Coast"s affiliate, East Perth.
He made his senior debut in round 13, kicking a goal in his first match, and remained in the senior team for the rest of the season.
Adamson is the son of Baseball Australia Hall of Fame inductee Tony Adamson.
