Oregon State moved up one place to No. 4 in this week's USA Today/ESPN national baseball coaches poll.

The Beavers (20-3) have won nine straight games after sweeping San Francisco in a three-game series this past weekend.

In the other rankings released Monday, OSU moved up one spot to fourth in the Baseball America magazine rankings, up two spots to third in the Collegiate Baseball newspaper poll, and up one spot to fourth in the National Collegiate Baseball Writers Association poll.

The Beavers now go on the road for two straight weekends, playing a non-conference series at Cal Poly and then opening Pacific-10 play at Arizona. OSU plays at Cal Poly on Saturday, Sunday and Monday. The Beavers visit Arizona for a three-game series starting March 30.
