"It was a hard fought victory, no question," said OU head coach Sunny Golloway. "Arlington played great. They turned some double plays to kill some rallies, made us hit some pitches and they executed. But I am proud of the way the guys fought."
Indeed, they showed some resiliency after trailing 3-2 into the seventh inning.
That's when Casey Johnson smashed a shot over the right field wall to notch it up at three.
"Casey hit a huge bomb to take some pressure off our hitters," Golloway said. "The way he came in the DH spot and hit the ball out with two outs was huge. It really lifted our club, and we needed that."
Certainly, it lifted a club that's been belting the ball but managed just four hits on this day.
"It was a great team effort today," Johnson said. "It took everybody to win. I was just happy I was able to get in there and fortunately, the ball went out of the yard."
The Sooners held the Mavericks scoreless in the next inning and then regained the lead in the eighth when left fielder Max White scored on a wild pitch with the bases loaded and catcher Tyler Ogle at the plate.
OU scored first in the contest, twice in the top of the first inning when first baseman Cameron Seitzer singled in a pair of runs.
But pitcher Jordan John gave up one in the bottom half of the first, although he induced an inning-ending double-play ball that prevented further damage.
The Mavericks managed to take the lead when an error on a potential double play allowed UT-Arlington to score a couple of runs in the third.
However, reliever Dillon Overton came in and shut the door, throwing 5 1/3 innings of shutout ball to go along with six strikeouts.
The Sooners now head to San Diego for a tournament with Tony Gwynn's San Diego State squad, along with games against San Diego and Cal.
