Oklahoma State, which had won eight games in a row in Tulsa before losing in 2009, appeared to be in good shape after the first four innings Friday night. Head coach Frank Anderson's team scored single runs in each of the first four innings to take a 4-0 lead.
In the first, OSU leadoff hitter Davis Duren singled and stole second base – his 29th stolen base in 34 attempts this season – before scoring on Nico Rosthenhausler's two-out single.
First baseman Dean Green hit the first pitch of the second inning from OU starter Zach Neal over the right-centerfield fence for his sixth home run of the season to make it 2-0 in favor of the Cowboys.
Cowboy shortstop Mark Ginther reached on an error in the third inning and scored on Kevin David's two-out single into left as the lead stretched to 3-0.
Josh Botts gave the Cowboys a 4-0 lead after singling into centerfield, stealing second base, and coming around to score on Duren's fly ball that dropped in front of OU rightfielder Cody Reine when he broke back on the ball before realizing it was not hit as deep as he thought.
The Sooners finally got to Cowboys starter Tyler Lyons in the fourth inning after the Oklahoma State left-hander had retired 10 of the first 12 batters he faced. OU leftfielder Max White took Lyons deep over the left-field fence to trim the Cowboys lead to 4-1 in the bottom of the fourth inning.
Things really went south for the Cowboy senior pitcher in the fifth inning. Lyons got the first out on a grounder to second baseman Davis Duren but then No. 8 hitter Cody Reine and No. 9 hitter Chris Ellison hit back-to-back solo homers.
It appeared that Lyons would get out of the inning without any further damage after Caleb Bushyhead grounded out to Duren, but Garrett Buechele doubled to right-center on a ball that OSU rightfielder Josh Butts just missed making a diving catch on. Cameron Seitzer then blasted the Sooners third homer of the inning, taking Lyons deep over the centerfield fence to give OU a 5-4 lead.
Lyons then retired the next six Sooners he faced – including striking out three in a row – before allowing a single to Bushyhead with two outs in the bottom of the seventh inning. Buechele stepped to the plate and delivered OU's fifth homer of the game – a two-run shot to left field – to make it a 7-4 game.
The Cowboys would not go down without a fight. Green was hit by a pitch in the eighth inning and pinch-hitter Luis Uribe stepped to the plate with two outs against OU reliever Jeremy Erben, and homered over the left-field fence to pull the Cowboys within 7-6.
Ginther singled with one out in the ninth inning but was forced out at second on Rosthenhausler's grounder, and David flied out to center to end the game.
The Bedlam series continues this weekend with two games at Bricktown Ballpark in Oklahoma City. The two teams meet at 7:05 p.m. Saturday, and again at 4:05 p.m. Sunday.
