Congratulations to Dunn on his achievement. Too bad it's essentially meaningless to the White Sox since this team is cemented in last place. We needed his bat in 2011 and 2012 when it might have actually have made a difference, but he turned out to be a colossal bust.
Hopefully his recent success will make it more likely that the White Sox can unload him. It depends on whether there are teams out there desperate enough for power to be willing to assume most of his remaining salary. It also depends on whether the Sox are willing to eat a portion of his remaining salary.
I realize that trading Dunn now would likely mean even more losses for the Sox this year, but I think it would be better for the team long term if they could unload him now.
