Southern Illinois University sophomore pitcher Sarah Harness has been named the Missouri Valley Conference Pitcher of the Week, the conference announced Monday.

Harness went 2-0 with a microscopic 0.64 earned run average in three appearances over the weekend to help Southern keep its 18-game win streak alive. The sophomore hurler threw 11.0 innings and allowed just one earned run on five hits- of which just one went for extra bases. The Bowling Green, Mo., native struck out 12, walked just one and limited opponents to a .147 batting average.

Harness went the distance in Southern’s 4-1 win over Austin Peay, as she allowed just one run on three hits while striking out eight. She entered in relief in SIU’s wins over Ball State and DePaul, and allowed just two hits in four innings of relief. In the win over DePaul, Harness entered in the fifth to earn the win, as she gave up just one hit while striking out three.

The MVC Pitcher of the Week honor is the third for Harness in her career and the second-straight weekly honor for the Salukis. Maddy Vermejan was named the conference’s Player of the Week last week.

SIU, who’s 18-game win streak is tied for the second-longest in NCAA DI, returns to action this weekend when it hosts Northern Kentucky, UIC, Creighton and St. Louis for the Saluki Invitational.
