The 30-year-old Spaniard was preparing to serve in his game against John McEnroe, but turned to the crowd when he heard the woman’s cries.
The mother, who was at the stadium in Majorca, Spain, looked distressed, desperately trying to tell people around her that she couldn’t find her daughter.
While the game was halted, security men at the ground went to help the woman.
Luckily, someone found her daughter nestled in the crowd just a few rows away.
The whole crowd cheered at the pair’s emotional reunion and Nadal was seen smiling.
Nadal, you hero.
