Wolfpack upped its lead to 2-0 after a Heat penalty gave the Wolverines an indirect kick from the Heat 20-yard line.
Wetzstein sent the ball right past the Heat wall and buried it into the left-corner of the net.
The Heat narrowed their deficit to just a single goal by scoring on a rebound shot after Wolfpack goalie Abby O’Toole had knocked down an indirect kick.
The goal was the first given up by the Wolverines in five matches.
At the 15-minute mark, a powerful kick by Caitlin Bartusick hit the top crossbar of the goal and dropped down just behind the line for the next Wolfpack goal, making it 3-1.
Minutes later, Wetzstein’s corner kick in front of the goal hit a Heat defender, but teammate Kaela Blanco was there to score and up the Wolverines’ lead to 4-1 at the half.
The teams battled through a scoreless second half until Valerie Stark netted the final goal late in the game.
Keana Collier, who played in goal during the second half for Wolfpack, had several diving saves.
Defenders Laney Ehlers and Taylor Oliver, stopper Katie Lespier, forwards Erika Faria, Skylar Wilson and Shelle Zito and midfielder Brittney Stevens, all made key contributions.
“This was a true team effort,” Wolfpack Coach Scott Wilson said. “Every player on this team worked hard for this win, and I’m proud of all of them.”
