West Virginia's Caleb Gindl doubled to score Eric Farris with one out in the bottom of the 10th inning to give the Power a 3-2 victory over the visiting Lexington Legends on Sunday.
Lexington's Matt Cusick and Brian Pellegrini hit back-to-back home runs to right field in the top of the third inning to give the Legends a 2-1 lead.
But West Virginia relievers Roque Mercedes and Curtis Pasma struck out 11 and gave up just three hits and no runs over the final 71⁄3 innings.
In that time, the Power tied the game when Farris scored off a two-out double in the fifth and won it when the West Virginia second baseman scored again in the 10th.
Farris led off the bottom of the 10th with a single off Legends reliever Fernando Abad. Zelous Wheeler followed with a fly-out but Gindl's drive into right field ended it.
Abad (0-3) took the loss after giving up two hits and striking out one in 11⁄3 innings.
Lexington's Robert Leonhardt (two innings) and Carlos Ladeuth (three innings) gave up one run apiece before Reid Kelly came on to strike out five in three scoreless innings.
