TOKYO — At first, it appeared to be just a fun hypothetical: What if Team USA put four of its biggest stars on the women's 4x400 relay team in Tokyo? What if it drew from runners in three different events to make a sort of super team?
Then, USA Track & Field announced the lineup for the final Saturday night: Sydney McLaughlin. Allyson Felix. Dalilah Muhammad. Athing Mu.
It's no real surprise what happened next.
With that star-studded foursome, the U.S. continued its reign of dominance in the women's 4x400 relay, cruising to gold in a time of 3:16.
