1989 Holland Series

The 1989 Holland Series was the second Holland Series. It used a best-of-seven format instead of best-of-five - the Series would revert to using best-of-five until the 2010 Holland Series returned to best-of-seven. Opel Nicols beat Brugman Keukens Neptunus, 4 games to 3, for their 12th and last Hoofdklasse title. It was the only 7-game Holland Series until 2014.
