Before tie-breaks were introduced, tennis sets could theoretically go on forever. The longest sets often ran for many more games than typical matches today. The tie-break was officially adopted in 1970 to shorten matches.
Can you imagine the endurance it must’ve taken to play those endless sets? The 1970 rule change definitely saved players’ energy—and probably their sanity too!
Yeah! I think matches back then could go on forever. Imagine playing for hours with no tie-break—exhausting! Though, it did make for some legendary battles.
