CHARLOTTESVILLE, Va (CBS19 Sports) -- Between her immediately family and those she shares the field with, St. Anne's-Belfield senior Tilly Matheson is the ultimate teammate.

"My dad played in college, my brother played so my whole family loves lacrosse," said Tilly Matheson. "I think honestly just when I was little I just loved my team, I loved being a part of it."

"It's hard to put it into words perfectly but the one word if I could sum up Tilly is teammate," said STAB girls lacrosse coach Carrington King. "She really will sacrifice all the time on and off the field for her best friends."

Tilly's knack for the sport was clear early, making varsity and an impact as an 8th grader.

"There was a game as an 8th grader," said King. "That's really when I knew Tilly was really special because throughout even at that young age, throughout the challenging game where girls two-three older than her were saying 'ok we're gonna be on the bus soon let's just finish the game.' Tilly never ever stops battling for her teammates and it's really for them so she's one of a kind."

From middle school standout to now a senior, It's all come full circle.

"It is the weirdest thing being a senior this year," said Matheson. "We have a really young team this year and having those girls look up to me being a captain, I can't even wrap my head around it. When I was in 8th grade those girls were the coolest people ever."

As a five year starter and one of the leaders on the field as a midfielder, Tilly was named All LIS as she leads the Saints.

"She has that rare combination of the ultimate competitor coupled with the best teammate in the world," said King.

Whether she is the one scoring, assisting, or cheering from the bench, Tilly's selflessness and joy for the game, makes her that ultimate teammate.

"Really just try to put everyone before myself," said Matheson. "I think I've been a very selfless leader these past two years and I think they would all say that about me. I love this team and I love being a part of something bigger than myself."

"When we show up, I always try to make sure our staff is bringing the best version of ourselves for this part of the day and she's a constant reminder that this is the best part of our day and the gift that being on a team is pretty special," said King.
