ESPN's Jim Bowden reports that the Diamondbacks and Paul Goldschmidt have agreed to a contract extension. The terms of the deal are not yet known. Goldschmidt hadn't been slated for arbitration eligibility until after 2014 and had previously expressed hesitancy at hammering out a long-term deal, but the two sides made up ground recently. The new deal figures to buy out Goldy's arbitration years and probably some free agent years, as well.
