Coming off a win over seventh-ranked Oregon State, Oregon will visit last-place Washington State for a three-game baseball series beginning Friday.

The Ducks are tied for fifth in the Pac-12 at 5-4 with all four of the teams ahead of them ranked in the top 10 of multiple national polls. Oregon (19-12) is up to No. 25 in the nation in the RPI after defeating Oregon State 12-8 in a nonconference game Tuesday.

Oregon has won its last three Pac-12 games after sweeping Utah two weeks ago before returning home to split a four-game set with Fresno State last weekend.

Oregon will throw left-hander Robert Ahlstrom (4-4, 3.79 ERA) in the opening game against WSU’s Brandon White (2-4, 4.64). Cullen Kafka (3-2, 4.57) will start Saturday for the Ducks against A.J. Block (0-4, 5.50) of Washington State.

Both UO coach George Horton and WSU’s Marty Lees have yet to announce a Sunday starter.

The Cougars (7-23) are 0-9 in the conference while ranking last with a .257 batting average and 126 runs scored as well as a 6.36 ERA.

Spencer Steer leads Oregon with a .342 average while Gabe Matthews is at .327 with a team-high three homers and 24 RBIs.

The Ducks will play a nonconference game at Gonzaga on Monday before returning home to face second-ranked Stanford, which leads the conference at 7-2.
