Randy Johnson, who signed with the Giants this past winter, believes that he's ready to begin the 2009 regular season and march towards 300 wins. "I feel good where I'm at now," said Johnson, 45, who is five wins short of 300. "Every pitcher goes through a tired arm, whether you are my age or 25. I'm not Nostradamus. I don't know if I'll have it again." The Big Unit is 1-2 with a 2.38 ERA in four spring training starts.
