De Jong played outrageously in the first set - using his speed to position himself well against Draper's power and having the confidence to wallop winners.
It was intriguing to see if he could sustain that.
A dip at the start of the second set indicated the momentum was shifting, but the Dutchman has regained control after being allowed back into the contest by Draper.
Now he has the bit between his teeth at the business end of the second set.
