Kelly finished with 35 assists and four aces, while Eich added 19 kills.
"Madison has been pretty beastly all season," said Hawks head coach Marietta Snyder. "She is a good passer, just a well-rounded player. She doesn't get too much into her own head. When she makes a mistake she moves forward. Justine is just steady, has great hands and has become a leader. Both are leaders for us and they do it with confidence."
With the victory Mountlake Terrace advances to face Ferndale, a team that Snyder took notice of earlier in the season.
"We saw (Ferndale) in a tournament back in October," Snyder said. "They're a scrappy team. They have an outside hitter that's strong and an outside hitter that runs for every single ball. They're going to give us a tough match."
The Hawks host the Golden Eagles on Thursday at 7 p.m., while Glacier Peak will battle Stanwood in a loser-out match at 5 p.m.
