OKLAHOMA CITY — Pistol Pete returned to Bricktown Ballpark Saturday, but he had little to dance about.

The postseason edition of Bedlam was Oklahoma’s party.

The third-seeded Sooners exploded out of a hitting slump with 18 hits and set a Big 12 tournament record for runs in their 21-6 victory over Oklahoma State.

The victory kicked a lot of offensive demons out of OU’s closet. In its first two tournament games — both losses — it had scored just two runs.

That doesn’t factor in the sweep OU (40-19) suffered at the hands of their Bedlam rival two weeks earlier. In that series, the Sooners were outscored 15-2 and shut out twice.

OSU starter Brae Wright tossed a complete-game shutout at the Sooners on May 13. But a lot changed in 14 days. He took the loss and fell to 8-3.

“I thought our guys came out today and took the fight to Wright, who has been very good against us,” OU coach Sunny Golloway said. “Our guys really took the fight to him.”

OU did something it hadn’t in its previous games against OSU (39-18) or in the tournament.

It claimed the early lead and blew the lid off its offensive struggles.

Ryan Rohlinger went 3-for-4 and drove in four runs and Kevin Smith went 3-for-5 with four RBIs. Both also homered and were among eight OU starters to drive in at least one run.

Daniel McCutchen (8-7) picked up the win for OU. He only threw five innings and allowed five runs. But for about the only time this season, run support wasn’t an issue for the senior from Norman.

In his seven losses, OU averaged 1.87 runs.

OU leadoff hitter Chuckie Caufield singled to lead off the game, setting in motion one of the most lopsided routs in Bedlam history.

He eventually scored when Aaron Reza was hit by an 0-2 pitch with the bases loaded.

“I was just trying to play my game,” Caufield said. “I know when I’m going good I’m getting on base. I was not going to be denied getting on base. I noticed the past two games, my uniform has been pretty clean. I’m a dirty ballplayer. I should always be dirty.”
