Well, why do some guys cramp easily and others do not?
Is it diet/drinks? Is it hydration pre-match?
Is it musculature? Genetics? Is it stress and the way a guy handles score? Is it breathing? Is it how efficiently a guy moves?
I think of cramps and I think of Michael Chang and Marcos Baghdatis. Shuzo Matsuoka.
Remember Pete after that 1995 Davis Cup match in Moscow? Ouch.
I think of guys who did not cramp much and I think of Federer.
