The Olympic fencing tournament has been marked by massive upsets so far.
The biggest one yet came Wednesday morning in Carioca Arena 3.
Eleanor Harvey, an unheralded Canadian who attends Ohio State, stunned the world's top-ranked foil fencer, Italy's Arianna Errigo, 15-11 in the round of 16.
Errigo was considered by some to be the top fencer regardless of weapon in the world. She was expected to take her place as Italy's next great Olympic champion in Rio after the retirement of Valentina Vezzali, a six-time gold medalist.
But Harvey's elusive style flummoxed Errigo, and the match quickly got away from the Italian.
