Larisa Latynina (1956–1960) and
Věra Čáslavská (1964–1968) and the first to do so non-consecutively. Lee became the first reigning champion since
Nadia Comaneci in 1980 to return to the Olympic all-around podium.
Event finals During the
vault final Biles won gold after performing her eponymous Biles II vault (Yurchenko double pike) and a Cheng. Carey won bronze after performing a Cheng and double-twisting Yurchenko. Biles became the second woman to win two Olympic vault titles after
Věra Čáslavská (1964–1968). During the
uneven bars final Lee won bronze behind
Kaylia Nemour and
Qiu Qiyuan. During the
balance beam final four of the eight competitors fell off of the apparatus, including both Biles and Lee. They ended up finishing fifth and six respectively. During the
floor exercise final Biles went out of bounds twice and incurred 0.6 points in neutral deductions. As a results she finished in second behind
Rebeca Andrade. Initially Chiles was given a score of 13.666, which put her in fifth place. Her coach
Cécile Canqueteau-Landi filed an inquiry which was accepted and Chiles score was raised by a tenth, giving her a final score of 13.766 which put her in bronze medal position. The
Romanian Gymnastics Federation filed an appeal with the
Court of Arbitration for Sport (CAS) which determined that the inquiry was filed four seconds past the 1 minute time limitation and therefore Chiles' score would revert back to 13.666, which put her back in fifth place. The
International Olympic Committee upheld the ruling from CAS. ==Post-Olympics==
