OU was forced to turn quickly – too quickly – to Wednesday starter Dillon Overton, which also led to an early call for closer Steven Okert, who came on in the fifth.
“They had to go to their bullpen, I'm sure, a lot earlier than they wanted to,” said Tigers coach Tim Jamieson. “And I thought the second left-hander (Okert), he didn't get as late into the game as they would have liked.
“And that's all related to starting pitching. Everything matters. Getting (Magnifico) out early was big.”
Still, the Sooners rallied, even as Mizzou's lead grew to 7-2.
Evan Mistich keyed a three-run fifth inning with a two-run double, before Garrett Carey drove in two with a single in the sixth to bring OU even at 7-7.
But the Tigers loaded the bases in the eighth, getting the eventual winning run on a double play groundout. Then they held on.
The Sooners started something in the ninth, with Mistich drawing a leadoff walk. After a sacrifice and a pitching change, Caleb Bushyhead walked on five pitches, putting the winning run on base.
Matt Oberste popped out, before pinch hitter Chase Simpson rifled a shot into right field. Bushyhead was thrown out at the plate, but umpires ruled that Simpson's hit had actually struck Bushyhead's heel on its way into right field, resulting in the third out.
And the Sooners could only watch as the Tigers dogpiled in Oklahoma City.
“We're heartbroken, don't get me wrong,” Golloway said. “I know it's been since 1997. Nobody wanted it more than we did, I promise you. I didn't sleep last night.
“Wanted it for our university. Wanted it for our program. Wanted it for our fans. We're big boys, we understand that you've got to get breaks. You've got to get lucky. We didn't get a lot early in the year and they seem to be coming our way.
“Since we didn't get one today, we tip our cap to our opponent and maybe we've got one stored up for down the road.”
