How much we have to hydrate out here in this kind of heat and humidity. I think the most I have ever taken down in one day of fluids is five gallons - a gallon per match. If we didn't replace our fluids, we would probably keel over and die.
I just think about what I am doing on my side of the net, which requires focus. Even after all the years I've been playing, I still get butterflies before each match.
