(CNN) -- Michael Chang is in the record books as the youngest winner of a grand slam but his French Open triumph in 1989 is largely remembered for one extraordinary moment in a last 16 match against Ivan Lendl. Few people gave the 17-year-old Chinese American much chance against the world number one and three-time French Open champion. The odds lengthened still further when the Czech took a two sets lead. But Chang fought back to level at two sets all, despite suffering from cramp at the end of the fourth set. "I actually knew I was in trouble at the end of the fourth because I started cramping. Our match was about four hours and 37 minutes and against Ivan on clay, that's a pretty long time," he told CNN.

I hit the underhand serve, @placeholder was kind of surprised about it, moved, kind of got squeezed in because of the spin and had to come in because the serve was so short.
