Portland, OR -

The Oregon School Activities Association has approved a reclassification plan that includes a major shift in Class 6A high school sports leagues.

The plan approved Monday includes bigger leagues for Class 6A and eliminates hybrid leagues in all classifications.

Under the new setup, all Portland public high schools will now compete at the 6A level for the next four years. It's a move designed to cut down on travel costs.

Other changes include Clackamas and Oregon City moving into a new eight-team Mount Hood Conference, competing with teams from Barlow, Centennial, Central Catholic, David Douglas, Gresham and Reynolds high schools.

Meanwhile, Newberg, Sherwood, St. Mary's Academy, Tigard and Tualatin will join West Linn, Lake Oswego, Lakeridge and Canby in the new Three Rivers League.

The decision to separate Oregon City from 93-year rival West Linn dismayed some. Meanwhile, West Albany supporters failed to persuade the OSAA to let their team stay in the Class 5A Mid-Willamette Conference with rivals South Albany and Corvallis instead of moving to the Class 6A Central Valley Conference.
