Laver beat Ashe, the Australian Open winner in the final.
Unless I am completely misconstruing, Roger Taylor beat Ashe in the quarters of the Sydney Dunlop: 6-3, 8-6, 6-4.
Laver beat Rosewall in the finals: 3-6 6-2 3-6 6-2 6-3.
And I would agree the field looks better than at the AO of 1970. I believe that the Dunlop deserves to be the "Australian slam" of 1970.
