There might be a game only feed in the 600s for the other markets since Flint, Grand Rapids, Lansing, Marquette, Toledo and Traverse City will likely be subchannel only. Alpena, whose locals are not carried, won't have any OTA clearance as their lone commercial station WBKB has the Big 4 on all of its subchannels, and none of those networks would agree to pre-emptions 3-5 nights a week during the entire season.
The 900s will return for the Women's U.S. Open Golf between 6/4-6/7 and Men's U.S. Open Golf between 6/18-6/21. There will also be 4K coverage of the Featured Groups on channel 105 both weekends.
