Sophomore right-hander Jake Irvin has been a big part of Oklahoma's success so far.
Irvin is 5-0 with a 1.16 ERA, striking out 42 and walking just eight in 31 innings.
After missing his scheduled start in last week's Big 12 opener against Baylor, Irvin is once again questionable this weekend when the Sooners host Texas Tech at Michell Park.
Coach Pete Hughes plans to start Dylan Grove and Devon Perez in the first two games of the series with the hopes that Irvin could pitch in Sunday's series finale.
