The governing body claims the agreement, which has an emphasis on the development of Baseball5, has been highly successful in its first 12 months.

Belgravia Group is Baseball Australia's first major partner of Baseball5 - a simplified version of the game which does not require bats or gloves. 

The agreement runs until the end of at least 2023, and Belgravia Group will be arranging competitions in leisure centres across Australia as part of the extended partnership.

"The first 12 months were mutually beneficial and that has us very excited about another three years," said Baseball Australia’s chief executive Cam Vale.

"The next three years present a huge opportunity to grow the relationship and benefit our sport across all levels, and that starts with Belgravia Group becoming Baseball5’s first major partner in Australia."

Belgravia Group chief executive Geoff Lord added: "Supporting sports like baseball helps communities to become active.

"It’s great to help grow grassroots baseball, and this contributes to our vision of helping 1,000,000 Australian kids to become active’."

Steve Pallas, chief executive of Belgravia Group’s recently acquired Sports Community, said the partnership extension would benefit all baseball clubs.

"At Sports Community, we are really looking forward to partnering with Baseball Australia to train, support and empower all baseball clubs and their amazing volunteers who will now get access to Club Spot, our extensive online training and volunteer resource library, webinar training programs, help and support," he said.
