The three-time defending champion,
Noah Lyles, was aiming to match
Usain Bolt's record of four World Championships gold medals in the 200. With a bye in the event, Lyles hadrun fewer races in the regular season, but still came in as the world leader. The two other favorites were
Letsile Tebogo, defending Olympic champion; and
Kenny Bednarek, with a collection of silvers over the last Olympics and World Championships. In the heats,
Bryan Levell was the fastest with 19.84, then
Tapiwanashe Makarawu 19.91 and
Courtney Lindsey in 19.95. In the last semfinal, Lyles ran a 19.51, ultimately faster than even the winning time in the final. The semis saw the elimination of several famous names including
Andre De Grasse, Lindsay,
Gout Gout, and
Wayde van Niekerk. The final went off with 5 men separating from the other three. Coming off the turn Levell had developed almost a 1-metre lead on Lyles and Bednarek, with Tebogo slightly behind them and Hughes still in contention. In just 10 quick steps, Lyles and Bednarek moved from behind Levell to a metre ahead. Down the straightaway, Lyles put a little more gap on Bednarek. Tebogo closed down as well but couldn't quite catch Levell. == Records ==
