The Blue Jays have voided the contract of Luis Castro after the Venezuelan shortstop did not pass his physical, according to a source familiar with the contract. Castro, 16, had agreed to terms with the Blue Jays for $800,000 when the international signing period opened July 2 and had ranked as the No. 9 international prospect. Since the contract was never finalized, Castro will not receive his bonus and will become a free agent.
