Day four at the Tokyo Olympics will be headlined by one of the most anticipated events of 2021 — the women’s gymnastics team final.
However, an upset win for Alaskan teen Lydia Jacoby in the women's 100-meter breaststroke provided an early highlight in Tuesday's action. Jacoby edged U.S. teammate Lilly King, the defending champion in the event from the 2016 Games in Rio. King ended up getting bronze, one of three on the day for American swimmers.
Another upset occurred at the Ariake Tennis Park Centre Court as No. 2 seed and Olympic cauldron lighter Naomi Osaka lost in straight sets to Marketa Vondrousova 6-1, 6-4.
