STILLWATER, Okla. — James Washington came into the season as the standout receiver for No. 6 Oklahoma State. Now he has a lot of company among the Cowboys’ talented group of wide receivers.

Four OSU wideouts, including Washington, recorded at least 100 yards receiving in Oklahoma State’s 59-21 victory over Pittsburgh, as Heisman Trophy candidate Mason Rudolph threw for 497 yards and five touchdowns, all in the first half.

That was the first time in school history more than two receivers reached 100 yards in the same game and the first time any team had four since Texas Tech in 2005.

“Going into the year, we felt good about the group we have, and they’re competitive,” Oklahoma State coach Mike Gundy said. “We’ve got young guys who are making plays. They’re unselfish. The depth allows us to save legs and keep them fresh throughout the game. Mason’s done a good job, with the exception of the one interception he threw, in distributing the ball, based on what the defense gives us.”

The Cowboys play their Big 12 opener Saturday against No. 16 TCU.

While Washington had five receptions for 124 yards against Pitt, he didn’t make his first catch until late in the second quarter, when Oklahoma State was already ahead 35-0. Pitt clearly made a tactical decision to eliminate Washington, one of the favorites for the Biletnikoff Award as the nation’s top receiver, as a threat, so Rudolph simply found other open receivers.
