Langosch reports that the Pirates would likely not have to part with top prospects to obtain Kubel. However, the big question is whether the Twins, at 6.5 games out, would move him. So far, indications are that the Twins still consider themselves contenders, or at least aren't interested in selling off pieces. The Reds and Mets are 6.5 games out as well.
Kubel, 29, is hitting .308/.359/.463 in 248 plate appearances this year. He missed all of June and three weeks of July with a sprained foot. He's got $1.76MM remaining on his contract this year and projects as a Type B free agent currently, at least in the American League.
