The Tigers have placed lefty Daniel Stumpf on waivers, the pitcher himself told reporters including Evan Woodberry of MLive.com (via Twitter). He was taken in the Rule 5 draft last winter from the Royals.
Because Stumpf was previously taken in the Rule 5 draft and returned to K.C. — last summer, he was shipped back from the Phillies — he’s in something of a unique situation, as Woodberry notes. If he clears waivers, Stumpf would have the right to reject an assignment with the Royals and instead take free agency.
