How many Dutchmen have won the Rotterdam title?

Question

How many times has a Dutch tennis player given the local crowd something to celebrate by winning the title in Rotterdam?

Answer 1

Tom Okker won the title in 1974, and it wasn’t until 1995 that another Dutchman, this time Richard Krajicek, won the title. Jan Siemerink made it back-to-back local titlists when he won in 1996 but there hasn’t been a Dutch champion since. So that makes a total of three.
