· The first Olympic Games featuring women's wrestling started at 9:30 a.m. at the Ano Liossia Olympic Hall in Athens, Greece, with competition on two mats.

With less than 20 seconds to go, Icho put Kartashova to her back during a scramble and emerged with a 6-2 win.    · Seven nations had full four-athlete teams in the field, but Japan was the only one with an undefeated first session.

Zygouri scored the go-ahead points in her 5-3 win late in the match, which placed her in the semifinals on Monday against Sara McMann of the USA.    · The nation with the largest fan contingent for women's wrestling appeared to be Japan. There is an organized cheering section, and the fans are wearing headbands and waving flags. There was also a large and vocal section supporting host Greece. The USA has a good section as well, which chanted "USA, USA" during a number of the bouts.    · The loudest noise in the arena came early in the second session, when there was a Japanese wrestler on Mat 2 and a Greek wrestler on Mat 1. When Maria Louiza Vyroni of Greece won her bout at 72 kg, while Saori Yoshida of Japan won her bout at 55 kg at the same time, the crowd was going wild.    · The U.S. has two officials working the Games, Rick Tucci of Florida and Bill Stecklein of New Jersey.    · Both of the wildcard athletes in the women's division are at 48 kg, Leopoldina Ross of Guinea-Bissau and Fadhila Louati of Tunisia.
