Hello Everett Aquasox, Seattle Mariners and Chris Bosio fans.  This is an official Northwest League ball that has been signed by Mariner and Aquasox pitch Chris Bosio.  The ball comes with a Certificate of Authenticity by Score Board, Inc as seen in the photo.
     Bosio pitched with the Mariners in the early 1990's throwing his 1st no hitter with the M's in 1993 against the Boston Red Sox.  By 1996 he was doing a re-hab assignment with the M's farm team the Everett Aquasox in Everett, Washington.  Thus, this autograph is on a Northwest League ball.  The autograph was signed with a blue ball point pen.
     Bosio finished his career with 94 wins vs 93 losses.
