Edwin Jackson has had a topsy-turvy career in the majors so far, as he has gone from Los Angeles to Tampa Bay to Detroit to Arizona, and not always had the most success. Nevertheless, he's also been a starting pitcher for a World Series team and he's thrown a no-hitter in 2010.
Not to be rose-colored about Jackson, but his 5.01 ERA in 2010 is deceptive. Since allowing 18 earned runs in back-to-back starts at Colorado and at Chicago in the last week of April and first week of May, he has a 3.99 ERA in 14 starts.
All of that said, the Washington Nationals are reported to be trying to do something very interesting: according to Ken Rosenthal at FOX Sports, the Nationals are trying to get young pitching talent in return for Adam Dunn, and then are going to try to swing that talent to the Diamondbacks in return for Edwin Jackson.
It looks like the Nationals are going to try to make themselves into the next dominant pitching force in the NL East.
And given their apparent lack of interest in holding onto Dunn, it also appears as though they have a plan in place for Bryce Harper.
