That puts a must-win feel on this weekend's home series against Kansas State.
K-State arrives in a first-place percentage tie with OU, looking to solidify its own postseason status.
Sooner ace Jonathan Gray continues to create buzz as a potential No. 1 pick in Major League Baseball's June draft.
The big right-hander was featured on the ESPN.com's MLB home page Thursday in a package on the draft. At the top, there's much-hyped Stanford pitcher Mark Appel.
From the website's Teddy Mitrosilis: “In a little less than two months, the No. 1 overall pick in the 2013 MLB draft will likely come down to two names: Mark Appel and Jonathan Gray.”

Matt Oberste, OU, 30

* UP: Cal Towey, 3B, Baylor
The Baylor senior has his team on the rise after powering the Bears to a series victory over Oklahoma last weekend. Towey delivered a walk off home run in Friday's 2-1 win over the Sooners, then banged a game-winning grand slam on Sunday in the eighth inning. Towel leads the Bears with six game-winning RBIs.
* UP: Dillon Overton, LHP, OU
Overton sometimes gets overlooked in the shadow of ace Jonathan Gray, but he's no ordinary No. 2 pitcher. More like a co-ace, evident in his 7-2 record and 2.20 ERA. Securing OU's one win in the Baylor series, Overton struck out eight over eight innings and allowed just one earned run.
* DOWN: Tech Pitching
Texas Tech boasts one of the Big 12's best arms in Trey Masek, who owns a 0.84 ERA. Which makes the team's league-worst 4.75 team ERA all the more ugly. No other conference staff has an ERA beyond 3.90. Tech has allowed a league-high 22 home runs and 189 runs overall in 326 innings.
* UP: Jordan Piché, RHP, Kansas
A transfer from Indian Hills Community College, Piché has been a saver, if not a savior for the Jayhawks. He recorded a win and a save in last weekend's series win over Texas – KU's first over the Longhorns in four years. He pitched the final 4 1/3 innings of Friday's 12-inning win and closed Sunday's clincher with 1 2/3 relief. He leads the Big 12 with a 0.49 ERA and is tied for the saves lead with seven.
