Grounds, a right-handed pitcher from Albany Creek, Queensland, Australia, brings both international and professional experience to the Bird Dawgs.

Before beginning his professional career, Grounds was selected to Australia’s U18 National Junior Squad and played as a two-way player for the Carina Red Sox during the 2021–22 Greater Brisbane League season.

Grounds signed with the Pittsburgh Pirates organization in 2022 and spent parts of four seasons in the Florida Complex League. In 2023, he appeared in 12 games and posted a 3.52 ERA. He also gained additional experience in the Australian Baseball League, appearing with the Sydney Blue Sox and Brisbane Bandits during offseason play.

On the international stage, Grounds has continued to represent Australia, most recently as a member of the U23 National Team that swept Guam to qualify for the 2026 WBSC U23 Baseball World Cup in Nicaragua.
