On June 28th, 2009 Mariano Rivera achieved his 500th career save. Rivera would go on to set the record for career saves at 652 by the time of his retirement. This OML from that game has been signed and inscribed by Rivera “500th Save 6/28/09”. In our opinion the autograph rates an 8. Accompanied by an ALOA from JSA. Presented to us as game-used and sourced from the game where Rivera had his 500th save.
