MANHEIM, Penn. — After a stellar performance in front of a hostile crowd of 14,000-plus at Gallagher-Iba Arena in Stillwater, Oklahoma, on Sunday, Penn State stands as the nation’s lone unbeaten team in Division I wrestling at the conclusion of the regular season. The 14-0 Nittany Lions won their second straight NWCA National Duals Championship and fourth overall by handing Oklahoma State its first loss of the season 27-13. The win secured PSU the top spot in the final USA TODAY/NWCA Division I Coaches Poll released on Tuesday.

The previous high for an Oklahoma State dual came of 10,082 came in 2001 against Oklahoma. The previous arena high was 14,044 during a 2007 Big 12 basketball game between Oklahoma State and Missouri.
