'Monkey' came to Collingwood from Woori Yallock and made his debut in 1988. The 202 cm, 116 kg big man was classed as a no.1 ruckman as soon as he got to Victoria Park, and his early career headed him to become a premiership ruckman in 1990. Monkhorst said that he was lucky to be playing in the Grand Final after fellow big man James Manson had a brilliant finals campaign, but Monkhorst dominated experienced performer Simon Madden after spending most of the first quarter on the bench.
