The White Sox and Diamondbacks are engaged in talks about righthander Edwin Jackson, according to the Chicago Tribune.
If acquired, Jackson could be flipped to the Nationals in a deal for Adam Dunn.
The Nationals and White Sox have been unable to agree on a trade to send Dunn from Washington to Chicago, but the Nationals are said to be interested in Jackson. Jackson is just 6-10 with a 5.16 ERA this season, but he fired a no-hitter against the Rays on June 25.
To acquire Jackson from the Diamondbacks, the White Sox likely would have to part with righthander Daniel Hudson, according to the Chicago Tribune. Hudson is scheduled to start for the White Sox tonight.
