The franchise was sold in 1991 and moved to Geneva, Illinois, where it became the Kane County Cougars.

Without an affiliation the team changed its name to the Timbers and played two years as a co-op with players mainly from the Cleveland Indians, Texas Rangers, and Seattle Mariners.

In 1981 the club signed a player development contract with the Mariners.

In 1990 the club signed on with the Baltimore Orioles and played their final season in Wausau.

The ballpark has hosted the Wisconsin Woodchucks of the summer collegiate Northwoods League, beginning in 1994.
