In 1989, the Eagle Pro Box Lacrosse League changed its name to the Major Indoor Lacrosse League.
The Wings also made a move on the field that season, winning their first league championship.
This was the first of a record six National Lacrosse league titles.
They recorded 7 wins and 2 losses while once again drawing upon an ever increasing home base, with a total home attendance of 74,876 (14,975 per game).
Star players Brad Kotz and Tony Resch led the team.
