Peter Gammons of MLB Network reports that the Twins have placed outfielder Josh Willingham on revocable waivers. Willingham is batting .214/.348/.393 with 12 home runs and 45 RBI over 87 games this season and made his return from right knee surgery earlier this month. The 34-year-old is under contract for $7 million next season. He could be an interesting bat for a contender, but his salary, health, and lack of production could limit interest.
