CBS Sports' Jon Heyman reports that Jose Valverde has agreed to a minor-league contract with the Diamondbacks. Papa Grande's career has derailed over the past two seasons, as he's posted a 4.18 ERA, 1.24 WHIP and 67/33 K/BB ratio over 88 1/3 innings. Things really bottomed out in 2013, when the 35-year-old posted a 5.59 ERA over 19 1/3 innings with Detroit. Valverde isn't likely to ever see the ninth inning in Arizona, as the Snakes have a host of pitchers that include Addison Reed, J.J. Putz, David Hernandez and Brad Ziegler ahead of him in the bullpen hierarchy.
