The Diamondbacks have a full rotation, but they could add depth, according to Nick Piecoro of the Arizona Republic. Piecoro suggests that any newcomers would likely arrive on minor league deals.
Joe Saunders, Ian Kennedy, Daniel Hudson, Zach Duke and Barry Enright give the D’Backs a solid starting five, but Kennedy, Hudson and Enright had not seen much big league playing time before 2010. GM Kevin Towers could look to add depth to a rotation that has lost Dan Haren, Edwin Jackson and Rodrigo Lopez in the past 12 months.
As MLBTR's Free Agent Tracker shows, Towers has plenty of options. Lopez, a free agent, logged 200 innings for the D'Backs last year, so he figures to look for a guaranteed starting job elsewhere.
