Another night, another full slate of surprises and triumphs at the Tokyo Olympics.
The biggest stunner came in tennis, where Japan's Naomi Osaka -- who lit the Olympic torch just days ago and was the tournament's No. 2 seed -- was ousted.
The U.S. women's basketball team began its quest for a seventh consecutive gold medal with a win over Nigeria. Sue Bird and Diana Taurasi -- who both boast four gold medals to their names -- have never lost in Olympic competition. Elsewhere, Team USA grabbed four more medals in the pool across four individual finals, led by Lydia Jacoby's gold in the 100-meter breaststroke.
