The Baseball NSW Major League is the highest level of play for the sport of baseball in New South Wales. It is currently composed of clubs predominantly from Sydney, with one club from the Central Coast.
The teams play a round-robin format of games that forms the regular season. The teams in each division are ranked on their win/loss percentage, dividing the number of wins (counting ties as a half win) by the number of games played. The five highest-placed teams from each division progressing to compete in their respective finals series in the post-season, to determine the four division Premiers. The finals are played at the neutral venue of Blacktown Olympic Park, one of the venues for baseball during the 2000 Sydney Olympics, and home of the NSW Patriots during the Claxton Shield.
At the end of the regular season, the Club Championship is calculated by:
The club with the highest total is declared the Club Champion.

The League expanded again in 1911 to three grades. Though First and Second Grades have both been contested continuously since their respective introductions, Third Grade initially only lasted until the 1915 season. It was reintroduced for the 1918 and continued through to 1941. The league expanded to three grades once more in 1944, and with the exception of the following year has continued as such since.
1973 was the final year that the League played during the winter months, as the Australian Baseball Federation decided to make baseball a summer sport. The move was designed to allow more favourable weather conditions for spectators and players alike, and to bring it in line with baseball in the United States. This saw the creation of the Sydney Winter League in 1974, and the first summer season of the NSW Major League played in 1974-75.
A Club Championship was introduced for the 1980-81 season, which was used to determine the best performing club over the three grades. Auburn was the first club to win the Championship, winning nine times in the first twelve seasons, though they have yet to win any since.
An Under 18s competition was incorporated into the League for the 1985-86 season, with Baulkham Hills the inaugural winners.
