Duffy finished 3 for 5 to lead a 12-hit attack by the Volcanoes.

Four Salem-Keizer pitchers combined for eight scoreless innings before Everett finally scored in the ninth.

Catcher Mike Zunino, the Mariners' first-round draft pick who came into the game 7 for 15 in his first four games as a pro, was 0 for 2 with a pair of walks.
