The ADO Lakers retired jersey number #21 in honor of former pitcher Bart Volkerijk. The ceremony took place last Sunday before their game against Mr. Cocker HCAW. Between 1974 and 1996 he played 332 games in 21 seasons for ADO. His 150 wins and 1,948 strikeouts are still the most in Hoofdklasse history. He also appeared in 71 games for the Dutch National Team, winning European Championships in 1981, 1985 and 1987.
