Scott Mathieson was taken off the active roster on July 27 because of discomfort in his right elbow. He was evaluated at a hospital in Tokyo on Saturday and was told he would miss about a month and a half. Unsatisfied with the diagnosis, he told team officials he wanted another evaluation.
The Giants announced today that Mathieson left Japan for the US in order to get a second opinion. He is also slated to return on August 12.
