OU (25-8) defeated No. 9 TCU 13-6 in the Norman leg of the yearly home-and-home matchup in a game that was basically over in the first inning.
The Sooners plated two runs in the first on a sac-fly by junior catcher Tyler Ogle and a throwing error with a runner on third by the Horned Frogs' catcher.
TCU (22-11) narrowed the deficit to 2-1 on an RBI double in the third and could have tied the game on a single with a runner trying to score from second, but junior center fielder Chris Ellison gunned him down to preserve the lead.
That catch seemed to be the turning point of the game when it looked like the Horned Frogs were building some momentum.
"I thought it was really big," said head coach Sunny Golloway. "They scored a run, and he came and made a great play. I mean, you look at the score and that's going to get real tight right there.
The Sooners plated three runs in the third – headlined by an RBI double by junior first baseman Cameron Seitzer – to start putting the game out of reach, and the floodgates opened when three more runs scored in the sixth.
The first of the three runs in the sixth crossed the plate on a suicide squeeze by Ellison with the bases loaded, and senior left fielder Casey Johnson, who was the team's leadoff hitter for the first time during his OU career, doubled on a sharp line drive to the left-field corner to bring in the other two runs.
The Sooners were able to score seemingly at will all day because of their sense of urgency.
"You know, it's now or never," Ogle said. "We can't keep waiting around. So, we made this game worth something. We made the message clear in the locker room that we were going to come out with a little more intensity."
Ogle brought in another run in the seventh inning with a leadoff no-doubt-about-it homer to left. The homer was his fifth of the season, which is the second most on the team behind junior third baseman Garrett Buechele's seven.
"I figured it might be my last at bat," Ogle said. "So I put a good swing on it."
The catcher from San Antonio, Texas, had one hit in three at-bats and drove in two runs.
The Sooners added four more runs in the eighth on a play off junior catcher Tanner Toal's bat that was a result of two errors by TCU fielders.
The Horned Frogs scored four runs in the ninth to prevent a double-digit-run loss.
Redshirt pitcher Jordan John was credited with the win although he only threw 47 pitches in three innings. Although he was held to a low pitch count, he made every pitch count as six of his nine outs were strikeouts.
OU will try to build off this big win this upcoming weekend against Oklahoma State in a three-game series that counts toward the conference standings.
Friday night's game will be played at 7:35 p.m. at OneOK Field in Tulsa, and the final two games will be at 7:05 p.m. Saturday and 4:05 p.m. Sunday at AT&T Bricktown Ballpark.
The Sooners defeated the Cowboys 8-3 in a non-conference affair in Norman on April 5.
"That midweek game last week was a good opener for us against them," said Ogle, who went 2-for-4 in the victory against Oklahoma State. "We kind of what they have, and they know what we got. "So, it'll be good. Good for the fans and good for the players as well."
