Since the Open era began in 1968, the US Open has provided many great memories from Arthur Ashe to Serena Williams. We count down the best by decade, starting with the 1960s/1970s.

But by 1970, with millions of fans tuning in, it did matter. US Open tournament director Bill Talbert liked the tiebreaker’s “definite cutoff,” and installed Van Alen’s brainchild.

That was how Bud Collins described his first sighting of an 18-year-old Connors at the 1970 US Open. He was making his debut as the “tagalong” doubles partner of his mentor, Pancho Gonzalez.
