Dickey was named the National League winner by the Baseball Writers Association of America after a storybook 2012 season in which he went 20-6 and led the league in strikeouts (230), shutouts (3), complete games (5), innings pitched (233.2) and games started (33).
The one-time journeyman's season was highlighted by back-to-back one-hitters in June. The 38-year-old was a runaway winner, named first on 27-of-32 ballots cast.
Price, meanwhile, emerged the winner in a close battle with Detroit's Justin Verlander for the AL honors in the tightest voting since 1969. The left-hander was named first on 14 ballots and second on 13 others, edging Verlader by only four points.
Price, a 27-year-old three-time all-star, compiled a 20-5 record with 205 strikeouts and a league-best 2.56 ERA last season while holding opposing hitters to an AL-low .318 slugging percentage.
