"We feel like we've got some momentum," said head coach Sunny Golloway. "Our guys are a little more excited about coming to the yard every day."
Center fielder Max White got the scoring started when he poked a 2-2 pitch into right center in the bottom of the first to put OU up 2-0.
"You know, these guys were throwing sliders all day," White said. "Just had to sit back on the off-speed and hit it the other way. That's been our approach lately and with guys in scoring position, I knew I had to get it in the air. I just got lucky and got the hit."
The Sooners left the bases loaded in the frame, but it wouldn't matter.
Catcher Hunter Lockwood laced a two-run homer over the left field corner wall on yet another off-speed offering to make it 4-0 after three.
"The wind helped me out a little bit tonight," Lockwood said. "Guy flipped in a little slider and fooled me actually. But hit and run, just trying to get the barrel on the ball and it floated out."
And that was it for the Sooners on the scoreboard, all before the fifth inning.
ORU added a pair of runs, one each in the sixth and ninth on RBI groundouts.
But despite that, OU really put the clamps on defensively not to let ORU get back in the game, something teams have been able to do against the Sooners early in the year.
Certainly not this time.
"That's exactly what it was about," Golloway said. "You know, when it was five to one, that's what I talked to the club about. I said, ‘Hey, we've been here before.'"
The victory in the first regular season meeting since 2004 between the two in-state rivals helped OU improve to 16-10 overall and 33-29 all-time against the Golden Eagles (10-13).
OU will get back to action when it hosts Kansas State at 6:30 p.m. CT Friday for the first of a three-game set.
