The Chattanooga Lookouts used seven pitchers, including five who have been in the rotation, to finally top Mississippi 3-2 in 12 innings on Sunday after opening the series with four straight defeats.
The Lookouts (11-13) loaded the bases in the top of the 12th inning on a J.T. Wise walk and with singles by Rafael Ynoa and Miguel Rojas before Wise scored on an Ozzie Martinez fielder's choice.
The game had been tied at 2-2 since the seventh inning, when former Lookout Jaime Pedroza singled to right to score Edward Salcido.
The Lookouts are off due to Southern League all-star festivities until Thursday night, when they will open a five-game series at Birmingham.
The Lookouts and Barons will set their rotations later in the week.
