Diamondbacks signed 1B Paul Goldschmidt to a five-year, $32 million contract extension with a club option for 2019. The deal was first reported by ESPN's Jim Bowden on Friday and is now official. Goldschmidt was already under team control through 2017, so the extension buys out his arbitration years and at least one year of free agency. The 25-year-old has quickly established himself as one of the top young first basemen in the National League and batted .286/.359/.490 with 20 home runs and 83 RBI in his first full season in the majors.
