PHOENIX -- When Zack Greinke was 25, he really only had to make one decision when he was on a pitcher's mound. Would he go with the 96 mph fastball or the nastiest slider of any right-handed pitcher in the league?He remembers the mindset of his Cy Young season, of feeling so dominant with his two pitches he could tell the hitter what was coming and still have a pretty good chance of getting him out.Pitching for a 97-loss Kansas City Royals team, nobody doubted who the best pitcher in the league was in 2009.
