The College Junior School has entered Softball teams in the JSHAA competition for some time. In order to continue apathway for those interested in the Diamond Game, the College entered teams in the Ryde Hornsby Baseball League for the 2007-08 season. Baseball was the first new sport in the secondary school in 30 years!

This arrangement with the College and RHBL is the first of its kind in Australia and offers the boys the highest level of competition in order to continue the development of their baseball skills.

In 2011/2012 the u14 team were Runners-Up and in the 2012/2013 season the College will offer three teams with U19, U16 and U14 age groups.

Home games will be held at the Major's Bay Reserve in Concord, whilst away games are located anywhere from Hornsby to Balmain.
