Rafael Nadal defeats Diego Schwartzman and advances to the Semi-Finals of the US Open 2019. The Spanish player said: ""I had stomach issues before match started. And I became dehydrated which triggered cramping. First in hand, then forearm.
Cramps continued to elbow and even into legs little bit. They started at the end of second set. After salt tablet kicked in, I felt better but knew he needed to finish the match quick."
