With a penalty shootout looming in hostile territory, Ashley Taylor and the Frontier field hockey team took matters into their own hands on Wednesday.

Taylor buried the game-winning goal with just three minutes remaining in double overtime, lifting the 12th-seeded Redhawks to a wild 2-1 victory over No. 5 Joseph Case in the MIAA Division 4 Round of 16 in Swansea.

It was the sixth consecutive victory for Frontier (11-6-4), which will look to stay upset-minded when it travels to No. 4 Sutton in the state quarterfinal round on Saturday at noon.

“We talk all the time about leaving it all on the field and really the mental component of this game... you have to be focused,” Frontier coach Missy Mahar said. “Collectively it took us a part of the season to figure some things out, but it’s really nice to see this team get this far and have this chance. They work extremely hard and I love to see them succeed.”

Taylor finished off an assist from Macy DeMaio in a scrum of players standing in front of the Case goal to seal the deal in double OT.

DeMaio scored the tying goal in the third quarter, helping the Hawks rally from an early 1-0 deficit when she buried an unassisted marker. It stayed that way through a 10-minute scoreless 7-on-7 overtime period and almost a second OT frame before Taylor won it.

“I think this game really came down to a lot of grit,” Mahar said. “We were down 1-0 in the first quarter and they just kept fighting back.”

Case (15-2-1) led 1-0 early when Bryant-bound star Megan Smith, the Boston Globe's reigning Division 4 Player of the Year, scored on a penalty corner. Frontier did a nice job limiting Smith’s opportunities the rest of the way, thanks in large part to the defensive work of Madison McKemmie. The senior blanketed Smith, along with some help from Whitney Campbell, and managed to keep the Cardinals offense off the board the rest of the way.

“We knew she was one of their biggest threats, with her ability to create scoring opportunities, so we knew we had to try and shut her down,” Mahar said of Smith. “Nothing but proud of the work and dedication Madison put into it. Along with Whitney Campbell who came on to give her some relief, the girls really executed the game plan.”

Next up is a Sutton (15-3-2) team that just got past Greenfield in overtime in the Round of 16 on Tuesday. A spot in the Final Four is on the line in central Mass.

“I know they’re a scrappy grass team so we’re excited about the opportunity,” Mahar said of Sutton. “Seeds at this point, it really only means who is going where, whether you have a home game or an away game in my mind. But I think it can go either way with a lot of these state tournament later-round games, you have to think you’re capable of winning these games.”
