1948 Claxton Shield

The 1948 Claxton Shield (at the time known as either the 1948 Australian Carnival or the 1948 Interstate Carnival ) was the ninth annual Claxton Shield, an Australian national baseball tournament. It was held in Perth, Western Australia from 7 to 14 August, and was won by Victoria for the second time overall, successfully defending their title from 1947. The other participants were South Australia, New South Wales, and hosts Western Australia.

Format
As had been the case in all previous tournaments where there had been four teams, each team played a round-robin schedule, meeting each other team once, with two competition points were on offer in each game. The points were awarded as follows: At the end of these preliminary games, the top two teams played each other to determine the champions, while the remaining two teams faced each other to determine third place.
 * Win – two points
 * Tie – one point
 * Loss – no points

All-Australian team
At the conclusion of the tournament, representatives from the Australian Baseball Council selected an All-Australian team. It was the fourth such Australian team selected at the end of a Claxton Shield tournament.
