Kenny Bednarek and Lyles, who won the silver and the bronze medals in the 200 meters on Wednesday night, did not participate in the relay. Lyles was part of the world champion team from 2019, and Bednarek said on Wednesday that he expected to be part of the relay team. Both could have taken part in the finals, as the rules allow countries to sub out runners between the semifinals and finals.
Strangely, the relay frustration for the American men is unique to the Olympic Games. They won the event at the 2019 world championships and earned a silver medal in the race at the 2017 world championships.
The Olympic frustration in the 110-meter high hurdles is somewhat less acute. Americans failed to medal in the event in 2016 but won two medals in 2012 and 2008.
Holloway looked to have the race under control early on, but in the second half he appeared to be rising too high over the hurdles, something that runners in the front can be prone to doing in order to protect themselves from hitting a hurdle while holding the lead.
The conservative strategy gave Parchment a chance to catch up, and he burned past Holloway in the final meters, edging him by five one-hundredths of a second, 13.04 to 13.09.
The American men are likely to spend the next several months trying to figure out what went wrong in Tokyo. There is little time to make adjustments, with Eugene, Ore., set to host the track and field world championships next summer.
