But that one-shot advantage was lost on Eaton, who didn't want to know anyone else's score.
"I didn't really know where I was," Eaton said. "I knew after  that it was going to be close but I didn't really want to find out exactly where I was."
Snodgrass did, and she was able to pull even with a solid par on the par-3 17th.
After Eaton bogeyed, it left Snodgrass staring down the 18th fairway with a driver in her hand and the entire tournament on her shoulders.
Yet she insists she never lost confidence.
"On the 18th tee we're tied, I'm first up, what am I going to do?" Snodgrass said. "I just have confidence that I'm going to hit my driver well. The last time I hit it I almost hit it out of bounds left, so I had to have confidence in it and come back with it, and that's what I did."
As for the putt that won the tournament?
"[Swing coach] Sarah [Yost] has this thing where I have to make 100 putts in a row from 3 or 4 feet and that's how long that par putt was," Snodgrass explained. "I've made thousands of these, hundreds even in a row, I was like 'I've got this. I'm just on the putting green listening to my music practicing again.' Just getting into that mindset and making that putt."
Snodgrass finished tied for seventh at last year's high school state tournament and earned all-state recognition.
She has spent her summer playing at various places around the country and is being courted by several colleges, including Marshall and UAB.
While her future is surely bright and Thursday's win was a big one, Snodgrass says all of her recent success is the result of her hard work.
"I've put in a lot of work and [Thursday's win] just validates that hard work does pay off," Snodgrass said. "When it was 100 degrees out I was out on the range working, and it just validates that."
Eaton's even-par effort was Thursday's low round.
