“Last season ended for me when I admitted taking a banned substance and accepted and served my punishment of a 50 game suspension. Since that day, my goals have been to serve my punishment and to put that mistake behind me, and to work hard to be the best baseball player I can be. At the end of last season, when it became clear that I would win the batting title despite my positive test, I asked the Players Association and MLB to make sure a more deserving player won, and I am very happy that my former teammate Buster Posey won that award instead of me.
I also accepted the Giants’ decision not to bring me back for the Playoffs after I served my punishment. Instead, I continued to work hard so I could be ready for the 2013 season. I hoped and expected that I would be allowed to put my mistake behind me and to start this season fresh.
