Round of 32
United States fencer Daryl Homer faced Ilya Mokretcov of Kazakhstan in his first bout of the day. Homer looked to be in control for most of the bout as he went on to win 15-11.
Teammate Eli Dershwitz trailed 4-8 at the start of the second period against Seppe van Holsbeke of Belgium. Homer had described Dershwitz as a "fighter" and his words proved true.
Dershwitz had a spirited comeback and got within reach of the veteran but van Holsbeke scored the final touch to beat the American 15-12.
Gold medal favorite Alexey Yakimenko of Russia took on 302nd ranked fencer Pancho Paskov of Bulgaria. The 22-year-old Paskov gave Yakimenko trouble late in the match, tying at 13 and going up a point on consecutive touches. The 2015 World Championships sabre winner came back to tie however it was Paskov that would come out on top in a tight 15-14 battle.
Hungary's Aron Szilagyi, another favorite to earn a medal, drew Mexico's Julian Ayala. Szilagyi won 15-9.
