DAYTON, Ohio -- After 40 minutes of give-no-ground basketball, everything opened up for Byron Eaton.
Oklahoma State's barrel-chested point guard found a clear path to the basket for a three-point play with 7.2 seconds left Friday, sending the Cowboys to a scintillating 77-75 victory over Tennessee in the first round of the NCAA tournament.
Oklahoma State (23-11) will play either East Tennessee State or Pittsburgh, the top seed in the East Regional. The Panthers sprawled across the first three rows of seats behind the Oklahoma State basket for the start of the second half, doing a little firsthand scouting.
They were gone long before Eaton -- a five-sport star in high school who also played a little football -- gave the game its final nudge.
He drove the lane untouched, leaned into Tyler Smith and drew the foul as his layup fell through the net and Eaton tumbled to the floor.
"I'm used to that contact," said Eaton, who added the free throw for his 20th point. "I jumped into him a little bit to protect myself and it went my way."
Smith had a chance to win it for Tennessee (21-13), but his jumper from behind the arc hit the side of the rim and bounced up to the top of the backboard as the buzzer sounded. Smith led all scorers with 21 points.
"I knew it was going to come down to the wire," Oklahoma State coach Travis Ford said. "If you study our team and their team, that was just the way it was going to be. We figured out how to survive."
Tennessee has reached the NCAA tournament in all four years under coach Bruce Pearl, who's had some of his best coaching moments there -- starting with his emergency stint as the Boston College mascot for one game in the 1981 tournament.
This wasn't one of them. He left the floor complaining to the referees that Smith was fouled on the final shot.
No matter how it turned out, this NCAA appearance amounted to a big step forward for Oklahoma State, which advanced to the Final Four in 2004, then fell on hard times. The Cowboys were relegated to the NIT the last three years, prompting them to hire Travis Ford as coach.
Even though it was a transition season in Stillwater -- Ford estimates that he's installed perhaps 60 percent of his offensive and defensive systems -- Oklahoma State was finally back playing with the big boys. His feistiness seemed to rub off on the Cowboys, giving them an edge they'd lacked.
Ford's fiery demeanor temporarily cost them on Friday.
Unhappy over a call, he took his complaint to the officials during a timeout and got a technical from Mike Sanzere. The two free throws were part of a five-point spurt that gave Tennessee its biggest lead at 32-25 and made Ford even more irate -- he berated Sanzere on the sideline a short time later and got an equally edgy reply.
With their free-flowing style, the Cowboys are accustomed to overcoming big leads and giving them away. Eaton hit a pair of pull-up jumpers in a 13-2 run that closed the half and put Oklahoma State up 38-34.
The stocky, 5-foot-11 guard also had a hand -- two of them, actually -- in a tone-setting moment during the run. He and Tennessee's Wayne Chism, a 6-foot-9 forward who weighs 242 pounds, wrapped their arms around a rebound and wouldn't let go. Chism yanked and they both tumbled to the ground, but Eaton refused to let give up the ball.
Ford liked that.
Oklahoma State tried to set the run-and-shoot style that made it one of the nation's highest-scoring teams. Tennessee stuck with its halfcourt game, trying to take advantage inside.
It was a stalemate -- 10 ties, 17 lead changes -- until Eaton, who was playing in his first NCAA game, found that final opening.
"It was one of my goals to get here and win some games. I just wish it had come a little sooner in my career," the senior said.
