The Tigers will designate Dontrelle Willis for assignment tomorrow, according to the team's official Twitter feed. The move will free up a roster spot for Max Scherzer, who is being called up to start tomorrow's game.
Willis, still just 28, has been a disappointment since coming over from the Marlins prior to the 2008 season. Overall he posted a 6.86 ERA in 101 innings with the team, including a 4.98 ERA in 43.1 innings this year. He won just two games in a Tigers' uniform, missing time with everything from knee hyper-extension to forearm tightness to anxiety disorder.
The Tigers have ten days to trade, release, or waive the former Rookie of the Year, but are still on the hook for his $12MM salary this season.
