The division plays with modified rules that encourages fair play and keeps the game moving.

Seasons of Play

Fall Baseball (September)

A time for development and fun. Fall baseball is comprised of player who will be entering the division in the following year as well as players who will be moving into their second year. This is typically players in grades 4 and 5. Subject to interest, there is opportunity to play teams from other associations.

Winterball (January-March)

Winterball is run in our first class indoor training facility: Sussex Insurance Centre on McArthur Island. Winterball is designed to offer the players instruction on many of the fundamentals that can get lost in the busy Spring Season. This back to basics approach gives players a fun environment to hone abilities and learn new aspects of the game and keep active during the winter months.

Registration opens in December each year and spots are limited.

Spring Season (April-June)

Given the large size of this Division, we are unable to offer set days of play. Players can expect about 2-3 practices/games per week. All players will be evaluated in early April and then drafted into their teams.

Each Friday night in May, KMBA offers an additional "Development Night" where players of all abilities work with some of KMBA's best players and coaches with the goal of getting better and having fun!

Registration opens in December each year.

Summer "Riverdogs" Season (July)

In May, players are given the opportunity to try out for one of KMBA's Summer Select teams. Each summer KMBA is dedicated to fielding as many summer teams as possible. These all-star teams represent KMBA as Riverdogs play in tournaments against other associations from around the province culminating with the provincial championship.

We try and field a Riverdog team at the following levels:

  • AAA Tier 1 - competitive
  • A (1st year players only) - competitive
  • AAA Tier 2 - development
