Arizona ace Zack Greinke referenced the projected top three teams in the NL West the other day, then quickly followed by saying he wasn't intending to slight the division's other two. Greinke mentioned the ''good competition between three teams'' following his first bullpen session Friday: The three-time defending West champion Los Angeles Dodgers, San Francisco and his own new club, of course. Relievers Jason Motte, Justin Miller and the underdog Colorado Rockies hardly mind any perceived disrespect at this stage, as they believe their improved pitching might just keep them in the mix in the loaded NL West.
