The Tigers and the Erie Seawolves came to a three year agreement that will keep the Seawolves as the Tigers Double-A affiliate through the year 2010. This came on the same day that the Seawolves agreed to a three year lease extension with the Erie County Convention Center Authority.  The Tigers haven’t changed any of their minor league affiliates since 2001 when they took on Erie and they have three more years with all of their remaining affiliates.
