After what looked like another near miss inning with Grossman being tossed out at second and Trevor Plouffe grounding out, Dozier jumped over a 3-2 pitch and brought in Joe Mauer for the walkoff blast to give the Minnesota Twins a 6-4 win.
The Miami Marlins (30-28) got the scoring started with a ground out by Giancarlo Stanton.
The Twins (17-40) came back and took the lead on a wild pitch after Nunez tied things up with a leadoff blast into the third deck.
Miami then took the lead after scoring three more runs off starter Pat Dean who went just 4 1/3 innings.
