TUCSON, Ariz. — J.D. Leckenby and a pair of relievers combined for a shutout as Washington State won its Pac-12 opener Friday 6-0 over No. 6 Arizona at Hi Corbett Field.

Leckenby scattered five hits, while walking three and striking out four in 6 1/3 innings. Richie Ochoa induced a double play to get out of the seventh and Kellen Camus recorded the final six outs for the Cougars (10-6 overall, 1-0 Pac-12). The win broke a six-game losing streak in Tucson against the Wildcats (14-4, 0-1).

The Cougars scored a run in each of the first four innings, as Derek Jones hit an RBI double, a Patrick Claussen RBI fielder's choice and an RBI single, and an Adam Nelubowich's sacrifice fly.

The shutout is the first by WSU against Arizona in a series that dates back to 1975. The teams will play a day-night doubleheader today at 1 and 6 p.m.
