Hayes gave West Virginia an early 1-0 lead. Hayes hit a 1-1 pitch from RiverDogs starter Yefrey Ramirez over the left field wall for his second home run of the season. The RiverDogs tied the game in the home half of the third inning on a run-scoring fielder's choice off Power starter Mitch Keller.
West Virginia regained the lead in the seventh. Daniel Arribas walked with one out and advanced to second on a wild pitch. With two down, Christian Kelley singled to center, driving in Arribas and giving the Power a 2-1 edge.
Charleston evened the score in the bottom of the ninth and pinned a blown save on Tanner Anderson. The reliever walked back-to-back batters in the ninth before allowing a base hit to Chris Gittens, driving in Hoy Jun Park from second to tie the game at two.
The Power loaded the bases with one out in the tenth without the benefit of a base hit. Hayes drove a fly ball to right. Jhalan Jackson caught the fly for the second out of the inning, but his throw home was off line as Alfredo Reyes scored the eventual game-winning run.
Keller worked seven innings of one-run, three-hit ball, striking out six and walking one, but did not factor in the decision. Anderson (1-1) earned the win after three innings of work while Claudio Custodio (3-1) was charged with the loss.
West Virginia and Charleston play the second game of this series on Thursday evening. Logan Sendelbach will start for the Power against the RiverDogs Anyelo Gomez. First pitch is slated for 7:05 P.M
