A top-10, prime-time showdown has drawn the first sellout in Boone Pickens Stadium history.

Oklahoma State announced Tuesday that the No. 10 Cowboys' showdown against fourth-ranked Baylor on Saturday night is officially sold out.

The single-game attendance record has already been broken twice this season in games against Lamar (59,061) and TCU (59,538).

And the crowd hasn't been bolstered by an influx of Baylor fans. An OSU source told The Oklahoman that Baylor did not request its full allotment of 3,800 tickets and then only sold about 700.
