SPRINGFIELD, Mass. — Defensemen Matt MacKenzie and Sena Acolatse scored third-period goals, and the Portland Pirates secured fourth place in the AHL’s Atlantic Division with a 3-1 win over the Springfield Falcons in their regular-season finale Sunday.

Mike McKenna made 35 saves for the Pirates, who will face the Atlantic Division champion Hershey Bears in the first round of the Calder Cup playoffs. The Pirates will host Games 1 and 2 on Friday and Saturday before the best-of-five series shifts to Hershey for three games, if necessary.

MacKenzie’s second goal of the season snapped a scoreless deadlock with 15:32 remaining. Acolatse made it 2-0 when he scored on a shot from the point during a power play with 10:08 left.

Craig Cunningham ended McKenna’s shutout bid just over a minute later, knocking in a rebound, but Connor Brickley clinched the victory with an empty-net goal in the final minute.

Game 1: at Cross Insurance Arena, 7 p.m. Friday
