Dodgers starter Zack Greinke opted out of his contract to become arguably the top free-agent pitcher on the market Wednesday. Greinke, 32, figures to command a significant raise from the $23 million he made last year. He went 19-3 with a major-league leading 1.66 earned-run average and a 0.84 WHIP, making him a favorite for the National League Cy Young Award.
