Jim Clark beats Emerson Fittipladi to progress to Round 21. Clark now faces the flying Finn, Mika Hakkinen.
For those new to this series, here is how it works. We started with those drivers who won a single championship, working through them chronologically. The winner of single champions will then face double champions, then triple etc... By the end of the series you will have voted for your champion of champions!
Remember you vote for the driver who you think would win in a One vs One situation.
The winner of this round will face Fernando Alonso in Round 22.
