Reno trailed by two runs entering the ninth, but Carlos Corporan would tie the game with a two-run home run to right-center. Doug Deeds would follow with a double and came across to score two batters later, capitalizing on a Tacoma throwing error with two outs in the inning.
In the home half of the ninth, the Rainiers battled back to even the score. Jack Hannahan smacked a run-scoring single that would knot the score at six and push the game into extra innings.
Reno and Tacoma would trade zeros over the next four frames before Everidge ended the proceedings with a two-run blast off Jose Marte in the bottom of the 14th inning.
Marte (0-2) took the loss after surrendering the walk-off home run, and Brian Sweeney (1-0) earned the win after holding Reno scoreless over the final 4.1 innings.
Corporan finished with three hits, three RBIs and two runs scored for the Aces. Pedro Ciriaco and Jeff Bailey chipped-in two hits apiece.
