NORMAN — Oklahoma didn’t wait to break out its backward pitching plan Friday night. Couldn’t wait. With OU ace Andrew Doyle roughed up early and yanked just one out into the third inning, the Sooners went to their pitching strength — the bullpen — and rallied for a 5-4 win over Wichita State in an NCAA Tournament opener at the Norman Regional. Before a crowd of 3,176 at Mitchell Park, top-seeded OU advanced to today’s winners’ bracket final, a 7 p.m. matchup with No. 2 Arkansas. The Razorbacks beat Washington State 10-3 in their opener. The scene wasn’t unfamiliar for the Sooners, who have leaned on their bullpen often this season. Still, it didn’t project as part of the script Friday night, with Doyle facing one of the weakest Wichita State lineups in memory. But with Doyle done after just 2 1/3 innings — his shortest outing of the season — OU sought relief and found it in Chase Anderson, who retired 15 of the 17 batters he faced before turning over the ninth inning to closer Ryan Duke. Combined, Anderson and Duke allowed just two hits and struck out eight. "We scored early,” said Shockers coach Gene Stephenson. "We did some good things early. "But when Anderson came in, he pretty much stopped us.” Wichita State, falling to 30-26, jumped Anderson for a first-inning run, then scored three more in the third for a 4-1 lead. Doyle might have gone on, except he drilled Ryan Engrav with a pitch after getting ahead 1-2 in the count. "It’s a tough decision, because Andrew Doyle has been so good all year,” said OU coach Sunny Golloway. "In a regular season game, even a Big 12 Friday night, I think he pitches through that. "We wanted to stay away from a big inning. We really believe in our club offensively, and we felt like we could respond, if we could hold them right there.” But this is the NCAA Tournament. And this, the bullpen, is where the Sooners turn in times of trouble. "Usually, Doyle goes out there and does his job,” said Anderson, who improved to 3-1. "But everybody has their days. I’ve got his back. We help everybody on this team. That’s what I tried to do tonight.” The Shockers were left lamenting an opportunity lost. "We went out there, and we roughed up their ace,” said WSU center fielder Ryan Jones, who doubled for one of four hits against Doyle. "We knocked him around pretty good. And then it seemed like we just sat back on our heels.” Once the OU bullpen came into play, the opportunities all but ceased. After Anderson ended Wichita State’s three-run third, the Shockers managed just three base runners the rest of the way and only one made it as far as second base. The Sooners got a run back in the fourth, with Aaron Baker’s home run cutting the lead to 4-2. Then in the sixth, OU surged ahead 5-4, knocking out Shockers starter Tim Kelley, a Tulsa Kelley product, with three runs, two delivered on a single by Garrett Buechele. Anderson and Duke finished the job, with the latter earning his 16th save, striking out two in the ninth.
