SANDUSKY, Ohio — One of college baseball's star pitchers is challenging the NCAA and its rules on agents.

The lawsuit in a northern Ohio courtroom could change how college baseball players deal with advisers and big league teams when they are drafted before their eligibility is over.

Oklahoma State ace Andrew Oliver was ruled ineligible just hours before he was to play in a tournament game last spring.

The NCAA suspended Oliver because they say advisers he had hired listened in on contract negotiations after he was drafted by the Minnesota Twins.

The NCAA allows players to hire advisers but says they can't contact any teams.

Oliver's attorneys say the NCAA shouldn't restrict a player's right to have legal help when negotiating a big league contract.
