OKLAHOMA CITY -- Oklahoma State took its third straight Bedlam Series with a second straight 4-3 win over Oklahoma (34-16, 11-9 Big 12) Saturday at Chickasaw Bricktown Ballpark.
The Cowboys (36-12, 11-8 Big 12) struck early and scored the game-winning run by stealing home in the eighth inning.
Sooner ace Jonathan Gray (8-2), held back one day from his usual Friday start, suffered just his second loss of the year as the Cowboys put their leadoff batter on base each of the first four innings and again in the last three.
"It seemed everything that could have gone bad went bad for me," Gray said. "I take full credit for that loss. I didn't give us a strong start."
Oklahoma State jumped to a 2-0 lead in the second inning after Gray hit Randy McCurry with a pitch and then Victor Romero knocked him in with a double to right center.
Gray recovered to strike out the next two batters, but Robbie Rea snuck a 1-2 slider just inside the foul line that tracked awkwardly in the corner of the right field wall, resulting in an RBI triple.
"We call it pitching with stress," OU head coach Sunny Golloway said about carrying the leadoff runners. "They're stressful pitches and they take a lot out of you and they drain you. The fact that he was still able to record 109 pitches was amazing because he had guys on the whole time. He had a lot of stressful pitches."
Gray began the fifth inning with a strikeout and groundout. Then the two-out RBI monster that has plagued the OU defense for the last few weeks woke again.
OSU's Donnie Walton, Tanner Krietemeier and McCurry hit three straight singles, with the last giving the Cowboys a 3-0 lead.
"It's very frustrating," Golloway said. "We haven't played bad, we just haven't played well enough to win.
"Even the pitch that was up hits the chalk line with two outs. There's been a lot of that for us. I think we've just got to keep going and stay mentally tough. I think the breaks even out in the long run and we'll get some down the road."
Hector Lorenzana gave the Sooners hope for the second straight day. After his home runs batted in all three OU runs in Friday's contest, Lorenzana singled to add two RBIs in the sixth inning.
Oklahoma State's Gage Green led off the eighth inning with a double that landed just in front of center fielder Craig Aikin, who kicked the ball into right field, allowing Green to reach third base. Green stole home on a 0-2 count as Jacob Evans' pitch sailed high of catcher Anthony Hermelyn.
Following a Max White single in the bottom of the frame, Lorenzana doubled to left field but White had to hold at third base. Garrett Carey scored White with a sacrifice fly, but Brendan McCurry retired the last four Sooners to clinch the victory.
Oklahoma began the weekend tied for first in the Big 12 standings but, with two losses, the Sooners have fallen to fourth with four games remaining.
"We can't look past tomorrow," Golloway said. "We have to secure a league win. It's important to us."
After missing two scheduled starts due to a forearm strain, junior lefthander Dillon Overton will take the mound for the Sooners in Game 3.
"I'll be excited to get him on the mound and see him pitch, to know that's he's healthy. Having a Dillon Overton down the road helps us in the postseason."
First pitch Sunday is scheduled for 1:05 p.m. The game will be televised on FS Southwest Plus.
