With the crack of the bat, the ball was gone. Washington National's slugger Bryce Harper knocking out his 100th home run, and first grand slam.
Idaho native Lauren Martin, who has been battling cancer for longer than Harper has been in the big leagues, made history in that moment too.
"We had been sitting there for maybe 5 minutes before that ball was hit," explained Jay Martin, Lauren's father.
The Martin family, Jay, Misty, and Lauren had purchased tickets to the game the day before, and even joked that their seats in right field were in the perfect position for a home run ball.
"Sure enough that's what happened," said Jay.
The family said they didn't even see who hit the ball, but before they knew it the history-making ball had landed in their section. Misty, Lauren's mom rushed to grab it.
"As I was grabbing the ball there was a mitt a couple inches away," explained Misty. I grabbed it and quickly stuck it in Lauren's lap."
Ten-year-old Lauren was just five years old when she was diagnosed with Leukemia.
At seven, the Make A Wish Foundation helped her fulfill her lifelong dream of meeting Taylor Swift in Portland, Oregon.
Now, three years later Lauren was being shaken off upstairs with security while her parents were still trying to figure out what was going on.
"At that point we were talking with the people around us and they said 'do you know who hit that?'" said Jay.
"Then the people around us told us it was Bryce Harper and that it was his 100th!"
Lauren gave the ball back to Harper, but the slugger made sure Lauren didn't go home empty-handed.
At a post-game meet-and-greet with Harper, he gave her a signed baseball bat.
Lauren says Harper was really nice, but it still didn't beat meeting Taylor Swift.
"I think I like Taylor Swift a little better because it was my dream but [meeting Harper] was cool too," said Lauren.
The Martin family had the baseball bat shipped back to their home in Lewiston where they said they should receive it Thursday.
Lauren, who is now in remission from her cancer said she plans on keeping it in her room.
