The WBBA Senior League is administered by the MYAS Gopher State Baseball League (GSBL).  There are varying levels of play, including AAA and AA.  Players consist of high school varsity players that choose not to play on their local Legion team; communities that do not have a Legion team; and players that just want to play baseball.

The Senior League (16-19U) is for high school age players who wish to play competitive baseball outside of VFW or American Legion.  The Senior League plays conference and tournament games against teams from the metro area.

Games and practices are typically held Monday through Friday. Players can plan on approximately 3-4 team functions (practices/games) per week. Regular season runs from June through mid-July, followed by a post-season tournament.

Rules and regulation regarding the U16 and 17-19U league can be found on the MYAS GSBL website.
