Guardado missed most of his senior baseball season at Nogales High School (LaPuente, Calif.) because of a shoulder injury he suffered while serving as the school's quarterback in the fall. He made just five starts during the baseball season, but his first matched him up against Peter Lambert, who was selected in the second round by the Rockies.
