ROGERS CITY, MI -- We have the story of a 13 year-old girl who didn't think twice about what she had to do and because of her quick thinking, another teenager is alive tonight.

Sarah Meredith says she's been swimming as long as she can remember, and over the weekend, that swimming helped save somebody else's life.

When not out on the water or playing basketball, 13 year-old Sarah is behind the plate.

“I'm a catcher, and I play first base too," she says.

Years of hard work and passion for softball have helped her become a pretty good player.  Wednesday, she was at a softball camp in Boyne City, polishing her game in front of some college scouts.

But it was across the street from her Rogers City house, near her home-field softball diamonds, in Lake Huron, where her passion met compassion which resulted in quick thinking.  Friday, she was swimming with goggles and scuba fins with her sister Rebecca and friend Paul.

“The girl, she just starts screaming, and I said, Rebecca, did you hear that?  And she's like yeah I do, and we look out, and there's this girl, and she's just like bobbing up and down in the water and I seen her once, she bobbed up, and spit up water," described Sarah.

Sarah broke away from her sister and friend and swam out 30 feet from the shore in the deep water to where the girl was panicking.

“I get out there, and I’m just like you got to stop screaming, just breathe, just breathe," she said.

But the struggling girl didn't stop.

“At one point, it was kind of scary, because she dunked me down once, and you know it's like how far is the water back, and you know, the fins kind of helped swim me back," said Sarah.

She made it back to shore safe, where the girl's mother breathed a sigh of relief.  So did Sarah.

“It's a good feeling knowing you helped somebody out, so yeah, it was nice," Sarah smiled.

And a proud moment for the family of the 13 year-old.

"I’m really proud of her, you know, you don't train people for stuff like that, and it has to come natural," said Dennis Meredith, Sarah’s father.

Overall, Sarah was pretty humble about the rescue, and she says right now, it's back to life, which for her is summer softball.  And to play off of her favorite sport, this weekend, she hit a walk-off homerun.

At Tuesday night's city meeting, Sarah was commended by the Rogers City board and they gave her a t-shirt that says, "I saved a life in Rogers City.”

Sarah says she hopes that's the only shirt she has to receive because she'd rather have softball champion t-shirts.
