Defense and free-throw shooting down the stretch earned the win for the host Tigers.
Heritage, which scored 20 points in the first quarter, tallied only seven points in the fourth period.
“I’m really happy with our defense in the fourth quarter,” Battle Ground coach Wes Armstrong said. “The guys communicated better and were in the right positions defensively. Our guys really dug deep.”
Battle Ground’s Devin Johnson led all scorers with 21 points and made some key free throws late to hold off Heritage. He also grabbed a team-leading eight rebounds. Nate Moring also hit some big foul shots late in the game. Kobe Ford had five assists for the Tigers (8-9, 4-5 4A GSHL).
Four players scored in double figures for the Timberwolves (5-13, 3-7). Payton Monda had 13 points, Mark Bejan 12, Kenese Peneueta 11 and Kevin Wilkerson 10.
