Oklahoma Baptist completed its three-game sweep of USAO Sunday, taking the Drovers 9-5 in Chickasha.
The Bison got eight strong innings from Doug Hurn, who took a shutout into the sixth inning, when USAO struck for four runs.
OBU had taken a 3-0 lead in the second inning on an RBI ground out by Billy Thomas and a two-run single by Christian Ruiz.
The Bison made it 6-0 in the fourth on a three-run home run by Josh Collazo, his ninth round-tripper of the season.
USAO got within two after their big sixth inning, but the Bison answered with three in the eighth on an RBI single by Ruiz and RBI grounders by Collazo and Chris Chambers.
Kyle Cooper and Mason Reilly led the Bison with three hits each, while Ruiz had two.
Now 15-1 overall and 6-0 in the Sooner Athletic Conference, the Bison step outside the SAC for a single game Tuesday against Briar Cliff before returning to the conference schedule this weekend with a Friday-Saturday, three-game home series against seventh-ranked Lubbock Christian.
