Oregon State pitcher Ben Wetzler must sit out the team's first 11 games under a penalty imposed by the NCAA.
Wetzler sought the advice of a representative from a sports management group following last summer's Major League Baseball amateur draft. The left-hander was selected in the fifth round by the Philadelphia Phillies, but he ultimately decided to return to Oregon State.
Wetzler, projected to be Oregon State's starter on Friday, is eligible to return on March 2.
The NCAA notified Oregon State that it was looking into the matter in November. The school and Wetzler cooperated fully with the investigation, Oregon State said in a statement Friday.
The Beavers proposed a penalty of 10 percent of the season, half of the NCAA's punishment. A school official called the decision ''too harsh'' given the circumstances.
