The Twins have agreed to a one-year, $1.5 million deal with slugger Jim Thome, a person familiar with the negotiations said today, adding that the deal includes up to $700,000 in incentives.

Thome, 39, has hit 564 career home runs, but the Twins signed him to bolster their bench. They already have Jason Kubel as a left-handed hitting DH.

Correction: The agreement would pay Thome up to $750,000 in incentives.
