KINGSPORT — The Mets turned around Tuesday night’s game with Bluefield in abrupt fashion. Trailing by four runs, Kingsport cut loose for seven in the bottom of the third inning and went on to capture a 10-4 Appalachian League win at Hunter Wright Stadium. The Blue Jays (32-22) had scored twice in each of the first two innings, totaling a half-dozen hits in the process. In the home half of the third, however, the contest underwent a marked change of complexion.
