WORCESTER – There’s a long lore of different field hockey dynasties across the state, but only Watertown had ever won four straight state titles in MIAA history entering this year.

Not anymore.

Behind Julianna Casucci’s hat trick on the biggest stage and its typical brand of well-rounded defense, top-seeded Uxbridge (21-2) secured a rare four-peat with a 3-1 win over No. 2 Monomoy in the Div. 4 state final Saturday at Worcester State.

Two of her goals came in the second quarter as the Sharks (20-1-2) played with more poise and execution than in the two programs’ meeting in last year’s state final.

“It always goes back to the players and what they put in, and what they deserve,” said Uxbridge head coach Kelly Rosborough. “To go four consecutive years in a row and join the ranks of some other amazing schools in Massachusetts, we’re just so proud and excited.”

“It’s amazing,” added junior Amelia Blood, who’s started in all four state finals. “It’s super exciting because this has never happened in Uxbridge history. We’re the first people to be able to do this. … I’m very thankful to have my teammates with me.”

The Spartans’ title comes before joining Div. 3 next year, capping off a historic 4-for-4 performance in Div. 4 that many of their starters were a part of for each one.

“It’s a feeling that will never get old,” Casucci said. “Even from our very first year, we didn’t know that was even possible for Uxbridge. After that, it’s been a goal every single year. … It’s so rewarding to be able to experience this because not everyone gets to experience it.”

Casucci’s scoring burst in the second quarter was critical, as Monomoy started action in a good rhythm by drawing three penalty corners. Uxbridge answered by applying pressure for much of the frame’s last seven minutes, but could only get two shots on goal.

That’s when Casucci dialed it up, firing a reverse chip for a 1-0 lead less than three minutes into the second quarter. She scored again on a tip about four minutes later for a 2-0 lead. Blood made a move to get to the circle and fired a drive toward the post. Casucci got into position in time to redirect it for the goal and the 2-0 lead.

“The defender was coming at me and I pulled left, shot it,” Blood said. “(Casucci) was there and tipped it, it was really amazing. (A hat trick in the final) doesn’t happen often. It was super exciting for her, I’m very glad she was able to do that.”

“(Casucci) captured the moments when she needed to and that was clutch for us today,” Rosborough added.

The play proved critical, with Uxbridge suffering a rare defensive lapse that led to a Monomoy corner at the end of the third quarter. Sam Clarke got the Sharks on the board with eight seconds left for what would have been a game-tying goal.

The Spartans didn’t let momentum build beyond that, though, getting back into the driver’s seat for much of the fourth quarter. And with under four minutes to go, Casucci finished off the hat trick before the defense iced the game.

“It’s more than the hat trick, it’s the team,” Casucci said. “Those goals wouldn’t have been possible without my team. … The feeling is great, I think the reward from the goals of getting to celebrate with my team, the feeling of celebrating is more rewarding than the actual goals themselves.”
