The Pirates might be interested in acquiring Matt Joyce or Jeff Larish in a trade with the Tigers for Jack Wilson.
I'd pass on Larish, who's already 26 and wasn't overly impressive last year in AAA. Joyce, who played well in both AAA and the majors last year as a 23-year-old, would be a good return indeed--probably way too good. I can't believe the Tigers would part with a young power hitter like that in exchange for Wilson, even if they took on some of Wilson's salary.
Pursuing someone like Joyce is a much better idea than someone like Cale Iorg or Danny Worth, but I'm not sure it's going to work out. The Pirates need to acquire upside here, but probably the way for them to do that is to acquire someone at the low levels of the farm system.
