On the first pitch to James, first-base umpire Randy Bruns said James swung when asked on appeal.
From his third-base coaching box, Hughes began yelling across the field at Bruns before second-base umpire Jeff Henricks ejected Hughes.
It was Hughes’ first ejection as an Oklahoma coach.
OU first baseman Anthony Hermelyn was also ejected in the 10th after striking out looking.
The Sooners took the lead in the fifth with a pair of runs, but Kindle Ladd, who had held the Longhorns scoreless for more than five innings, finally tired out in the seventh. Ladd gave up a pair of runs to tie the game.
Oklahoma’s bullpen hadn’t given up a run in more than 24 innings before those two.
“You can’t blame then,” James said of the bullpen. “They did a really good job. That’s a really good team over there.”
The emotional rollercoaster was tough for both teams, Sooner hitting coach Mike Anderson said.
“There was just a lot of emotion on the field tonight and you know the good side of that is our kids did a great job of getting back in it,” Anderson said. “The bad part of it — we want to finish it. Our kids are disappointed. Getting back in it — fighting back in it — that’s good stuff but finishing that game, they’re disappointed and they should be.”
