Juan Martín del Potro’s years of injuries have dropped his once-top-five ranking down to #141, but the Argentine showed the skills that marked his early career in downing the world’s #1 player, Novak Djokovic, in straight sets—a result that earned del Potro a lovely embrace and some words that brought him to tears.

The last time these two matched up in a major event, it was the 7-5, 4-6, 7-6, 6-7, 6-3 mindbuster at Wimbledon in 2013. Del Potro’s excelled in the Olympics before; he earned bronze in London (beating Djokovic). We’re happy to see him back, and we’re happy to see that Olympic tennis is still (inexplicably) awesome. Djokovic, for his part, left the court in tears:
