The Medal CountThe sweep by the U.S. women marked a significant first in Olympic history.
According to the Olympic historian Bill Mallon, there had been 61 such American track and field 1-2-3’s in prior editions of the modern Games, dating to 1904 (in events such as the 200-meter hurdles, which back then was a thing). The most recent U.S. 1-2-3’s: the 400 and 400 hurdles at the Beijing 2008 Games.
All 61 were in men’s events.
Wednesday night thus made for the first medals sweep for American track and field women.
