The shortest tennis match in history lasted 5 minutes - Apparently.
On May 15, 1997, at the US Open, Nicolas Pereira and Grant Stafford played a tiebreaker in the first round. Stafford won 6-0, 6-0, 6-0, but the match was stopped after just 5 minutes due to rain. The entire match, including the warm-up, lasted a total of 5 minutes. The fact is verifiable through the official US Open records and news archives from that year.
