The 26-year-old Jackson would be a project for Sox pitching coach Don Cooper, as he has a 5.55 ERA, 8.1 K/9, and 4.3 BB/9 on the season despite throwing a no-hitter in late June. Of course, we're not positive the hard-throwing righty won't be flipped, possibly for Adam Dunn, before Saturday's trade deadline. At any rate, Arizona shed more payroll with the move since Jackson is owed $1.5MM more this year and $8.35MM in 2011 before he'll be eligible to become one of the youngest members of the 2012 free agent class.
Hudson, 23, rocketed up Chicago's farm system last year with "three solid pitches and natural deception," according to Baseball America. He's spent most of this season in Triple A, posting a 3.47 ERA, 10.4 K/9, and 3.0 BB/9 with 13 home runs allowed in 93.3 innings. The D'Backs might be concerned that their revamped rotation is built around flyball pitchers, with Ian Kennedy and Joe Saunders already in the fold, but interim GM Jerry Dipoto told MLBTR, "pitchers with good stuff work just about anywhere" while noting that Kennedy and Hudson miss bats. The D'Backs will have Hudson under team control through 2016 even if they keep him in the Majors the rest of the season.
Holmberg, 19, was drafted in the second round, 71st overall out of high school by the White Sox last year. The southpaw was ranked eighth among Sox prospects by BA heading into the season, with the projection of a "middle of the rotation workhorse at best."
Ken Rosenthal and Jon Paul Morosi of FOX Sports were first to report the teams being on the verge of the deal, with Yahoo's Tim Brown breaking news of the agreement. Jon Heyman, Joe Cowley, and Bob Nightengale also contributed to the story.
