And last season, after weaving through a tough bracket, the Tigers were a surprising finalist again. An upstart seven-seed facing powerhouse Texas A&M.
With a chance to make the NCAA Tournament, Jamieson's squad led in the ninth inning again and had its heart broken again, blowing the lead and losing on a walk-off home run in the 10th.
So you can imagine Jamieson's worry on Sunday afternoon, when another improbable run had landed his sixth-seeded Tigers back in the championship game. Back in a dramatic ninth inning, clinging to an 8-7 lead over Oklahoma.
But this time, the wild ending went his way.
OU's Chase Simpson hit a two-out liner that drilled the foot of base runner Caleb Bushyhead, before trickling into right field. Despite an unnecessary play at the plate, the game was already over.
When the ball struck Bushyhead, Jamieson finally had his Big 12 title. And he could leave his beloved conference a happy man.
“We haven't had a lot of those at Missouri and we haven't had any in baseball,” Jamieson said. “So it meant a lot. We have been so close, right there, and we finally got over the hump. It's special in so many different ways.”
