6:59pm: The Diamondbacks have officially announced the signing.
Hudson, 26, saw his 2012 season cut short by a torn ulnar collateral ligament in his throwing elbow that required Tommy John surgery. After working his way back to health in 2013, Hudson took the mound in a rehab start in early June. That outing lasted just two innings, as Hudson was once again hit with the devastating news of a torn UCL. He underwent his second Tommy John surgery this summer and was non-tendered by Arizona last month.
Hudson had enjoyed a breakout campaign in 2011, totaling 222 innings of 3.49 ERA ball with 6.9 K/9 and 2.0 BB/9 for the Diamondbacks. Originally acquired along with the recently traded David Holmberg in a deal that sent Edwin Jackson to the White Sox, Hudson has a 3.68 ERA in 381 1/3 career innings at the big league level. Hudson stated a preference to remain with the D-Backs shortly before his non-tender. General manager Kevin Towers recently told reporters, including MLBTR's Zach Links, that he hoped to work out a new deal with Hudson.
