Thank you for the interesting question.
No, Hoad never, as an amateur or pro, dominated a year like Tilden did in the early twenties, when there was no real competition.
I would suggest that Hoad's year in 1959 was superior to any other year by another player, winning two pro majors and a head to head with Gonzales, including the overall Ampol world championship against a tougher field than McEnroe or Connors faced. The strength of the field was unparalleled.
Interesting you wrote that.

Yes I didn't include the tour but you already know the record there which is 42-20 won-lost with Gonzalez, Anderson and Cooper. Gonzalez finished 47-15 but lost his head to head 13-15 to Hoad.
Incidentally which two Pro Majors did he win?
