You are dehydrated
You can spit... then see if your spit is bubbly or clear. The more bubbly it is, the more dehydrated you are. Of course, if you feel thirsty it is a clear sign you are already dehydrated.

Trust me this happened to me when I played softball it was in the high 80s, it was my turn to bat I felt so weak I couldn't hold the bat straight. The coach lead me underneath a tree gave me a big water bottle I was done when the next person was up to bat!
