A perfect 4-0 record in the Pacific-10 Conference puts Oregon as one of two teams to go undefeated in Pac-10 play this season.
The Ducks have wins against Oregon State, Portland State, Stanford and California-Davis for their undefeated conference record.
Leading Oregon along its way are four Ducks — two sophomores and two seniors — who, between three national polls, appear in the top 20 rankings for their respective weight classes.
The top-ranked Duck, sophomore Shane Webster, is ranked in all three polls. The Wrestling Mall puts Webster at No. 13, while both W.I.N. Magazine and Amateur Wrestling News have Webster sitting at No. 11.
Sophomore Martin Mitchell is ranked No. 20, by W.I.N. Magazine, in the 125 weight class.
At 141, senior Casey Hunt is ranked No. 19 by The Wrestling Mall.
Fellow senior Tony Overstake, at 149, is ranked No. 17 by W.I.N. Magazine and Amateur Wrestling News.

What’s the score?
For an idea of how to score a wrestling match, it must first be understood that there are two different aspects to score.
The different weight class matches have a score, and from those scores, a meet score — and winning team — can be translated.
Each of the 10 weight classes has a match between two wrestlers. The wrestlers score points by earning takedowns on their opponents and escaping when they suffer a takedown, among other things.
At the end of each weight class, a score is added to the team total. If a wrestler earns a victory by defeating his opponent in points, it is a three-point decision. If the wrestler outscores his opponent by 8-14 points, he earns a four-point major decision for his team.
If a wrestler pins his opponent, he earns six points for his team. If the opposing team forfeits a match, the wrestler also earns six points.
