I thought it might be fun to see Okker's head to head against top players of his time. This is from the ITF website except for against Stan Smith which I got from ATP website.
Against Stan Smith
Okker is negative seven against all these top players. Some of the matches were played after Okker was in decline but to be fair he played some top players like Pancho Gonzalez when Gonzalez was past his prime. Pancho Gonzalez was still very tough (top ten at times) but pass his prime. He was very competitive usually against Laver but Laver usually won but you would expect that from Laver. Take away Laver and he's above .500 against everyone.
