Two of the three Michigan-based Midwest League teams are getting new fields this offseason.

Dow Diamond is getting a new playing surface for the first time since the Midland stadium was built in 2006. It is the home of the Great Lakes Loons, who won the Midwest League Championship Series this year and will host the Midwest League All-Star Game next year.

Cooley Law School Stadium also is getting a new field for the first time in 11 years. The home of the Lansing Lugnuts has been undergoing extensive renovations since after the 2014 season. The ballpark was known as Oldsmobile Park when it opened in 1996.
