Keegan Davis earned the last bid for the Oregon State wrestling team to NCAA tournament at 157 pounds.
The brackets were released Wednesday with 39 Pac-10 entrants of the 330.
OSU wrestlers must work their way through 32-man brackets after the pigtail, wrestle-in, rounds in some of the weight classes. The event runs March 18-20 in Omaha, Neb.
Davis, a senior with a 34-10 overall record, finished fourth at the Pac-10 Championships, just shy of the automatic bid to nationals. This is his second trip to the NCAA tournament, after qualifying as an at-large bid last season, too.
OSU already qualified redshirt sophomore Jason Lara (125 pounds), sophomore Kelly Kubec (133), redshirt freshman Mike Mangrum (141), junior Colby Covington (174). and sophomore Clayton Jack (heavyweight).
Jack and Kubec are the only other returners to the national tournament.
Covington is the only seeded wrestler for the Beavers at No. 8. He faces Jim Resnick of Rider in the first round. Davis faces Kyle John of Maryland in the first round.
Jack faces No. No. 5 Daniel Erekson of the Iowa first; Mangrum faces unseeded Mike Koehnlein of Nebraska; Kubec faces Jimmy Kirchner of Rider, and Lara faces Eric Morrill of Edinboro in the pigtail round.
