The flyweights have finished up their semifinal bouts this afternoon in London, and the gold medal match for Sunday is set.

Tugstsogt Nyambayar (Mongolia) def. Misha Aloian (Russia), 15-11: Another upset, and now the 20-year-old Mongolian goes for gold. Aloian was the No. 1 seed and favored by many to win the gold at the start, though Cuba's Robeisy Ramirez had picked up some steam as a possible favorite during the tournament. Nobody's really thought about Tugstsogt, but here he is, and he's got his shot. When he was 17, Tugstsogt beat Aloian in Milan at the Worlds, too, in the semifinals. Repeat, not revenge.

Robeisy Ramirez (Cuba) def. Michael Conlan (Ireland), 20-10: Conlan, like pretty much everyone the 18-year-old Cuban has fought, is good. And not on Ramirez's level. This kid is a special talent, and if he manages to turn pro within the next five years, he could make some huge noise in the lower weights. For my money, he remains in the running for the outstanding boxer of the tournament award. He's really something.
