34 year old Sal Perez had a crazy rebound season, Witt made his star turn. Those are the only two offensive players on their payroll with a contract beyond this season. The rest are UFA or under control.
They signed Wacha to a Flaherty deal and Lugo to a Maeda deal.
They haven't had debllitating injuries to their lineup and their best players have produced. I'm pretty sure the Tigers could have done that if Tork didn't implode and they didn't get decimated by injuries.
