Designated hitter Jeimer Candelario drove in three runs with a shot over the right-field wall to give the Hawks a two-run lead after the first inning Friday night at Memorial Stadium.
The Hawks didnt trail after that, and went on to a 6-4 victory over the Eugene Emeralds.
Hawks closer Bryce Shafer made it interesting in the ninth inning, loading the bases before inducing a double-play ground ball that ended the contest.
Gioskar Amaya was a one-man wrecking machine for Boise. The second baseman went 4-for-4 with two RBIs, two stolen bases and one run scored.
Boise improved to 3-5 after winning back-to-back contests for the first time this season.
The two teams play the fourth game of a five-game series Saturday night.
