Rafael Nadal is officially OUT of the U.S. Open ... the tennis legend said Tuesday it's just too damn unsafe for him to travel to America during the COVID-19 pandemic.
"The situation is very complicated worldwide," Nadal wrote in a statement. "The COVID-19 cases are increasing, it looks like we still don’t have control of it."
The world's No. 1-ranked player added, "This is a decision I never wanted to take but I have decided to follow my heart this time and for the time being I rather not travel."
The annual tournament is set to begin in just a few weeks on Aug.
