As World No.3 Rafael Nadal prepared to serve to South African Kevin Anderson in Round 4 of the Australian Open, an eagle-eyed ball-boy noticed something that could ruin Nadal's form.
Without hesitation, he dashed to the other side of the court to fix the dire situation.
The ball-boy knew exactly how the Spanish superstar, legendary for his backhand strength as much as his fastidiousness in superstition, likes his bottles arranged.
Precision.
Nadal smiled, attempting to prove he's not bothered at all.
