Johan Santana was the winning pitcher the last time before today. Johan hasn’t played baseball since 2012 and hasn’t been a Twin since 2007. The Twins have made the postseason 6 times(not including this year) since they last won a game.
And, correct me if I’m wrong, but @Ty_in_Tampa said they are building the new ballpark in a suboptimal location.
My understanding is that they are going to do something similar to what the Met, Yankee, and Cardinal have done and build the stadium up against the current one and then tear down the old one when the new one is ready. Then develop the area of the old stadium.
