WINTHROP – There was some concern whether the Winthrop/Lynn girls hockey team might have some rust when it played its first postseason game Saturday against Arlington.The Bulldogs hadn’t played in nine days, while the Spy Ponders were coming off a 2-1 overtime thriller against Barnstable earlier in the week.But Winthrop/Lynn skated through it for a 2-1 shootout win in Division 1 girls action at Larsen Rink – ensured only after goalie Katie Burt forced defenseman Hannah Wright to fire wide on Arlington’s final chance.”I felt that we had the advantage because of Katie,” said coach Anthony Martucci “She’s one of the best goalies in the state, and she did what she did best.”The shootout’s only goal came courtesy of Taylor Brown, who beat Arlington goalie Casey Schaejbe with a wrist shot on the team’s third opportunity, with the puck trickling past the goalie and into the net.Lynn/Winthrop plays later this week in the quarterfinal against either Medway/Ashland or Braintree.”(Brown) got a head of steam, and took the shot,” Martucci said. “She took it solidly, and it crossed over. It was a beautiful goal.”Arlington applied constant pressure on the ‘Dogs (16-3-1), but Burt kept Arlington at bay. However, Spy Ponder forward Kristin McKenzie flicked a 15-foot wrist shot to the short side to even the score at 1-1 midway through the third period.Both squads had chances for the victory in the 12-minute overtime, with perhaps Winthrop/Lynn’s Courtney McTague having the best shot. Brown stole the puck near mid-ice, skated into the Arlington zone and slid the puck to McTague, who was standing in front of the Spy Ponders net. But Schaejbe gloved the shot for the save.Wright had a good opportunity to give Arlington (15-6-1) the win, but Burt held her ground and kept the score tied.Arlington had the best chances in a scoreless first period. Burt foiled Kelsey Russell’s 20-footer on a two-man power play and did the same on Michelle Reilly’s 15-foot slap shot.Both teams had solid chances in the second period and it looked as if the score would be deadlocked heading into the third. But Brown beat Schaejbe with a 20-foot slap shot from the left side with 57 seconds left to give the Bulldogs a 1-0 lead.Both goalies continued their stellar play throughout the third period, though McKenzie evened the game with just under six minutes left. Each team was foiled in the overtime, setting up Brown’s shootout heroics.
