His hard work certainly paid off.
"When I was younger I was very little, so I knew that one day if I continued to work and get bigger it was going to pay off for me," he added. "I saw that happen this year."
It paid big dividends for he and his team. Peavy led his team with an unthinkable .566 average, and a .916 slugging percentage. He also hit five home runs and had 46 RBIs.
Incredibly, he put up these eye-opening numbers all while playing almost every position on the field.
"I played third, short, second, left, right, catcher and pitcher," he said.
The bad news for opponents is that he sees himself not bouncing around from position to position as much which will allow him to focus more on his hitting.
"Next season they told me my position would be mostly center, and pitcher," the rising senior said. "I really don't have a favorite; I just like playing them all. I can be used anywhere, but I am glad I get to concentrate on one position and focus there next season."
Peavy had a bit of a setback heading into the playoffs this season because of a broken rib.
"Before the playoffs, I thought it was just a strained muscle so I played all the way through," he explained. "I was going to pitch in one of the playoff games but I couldn't even throw because my rib was so sore."
How is it now? "It is healed, just not all the way through," he said. "I am able to swing and throw like normal now, though."
He is putting it to the test as his summer season has gotten underway.
"I have been playing some summer league ball," he said. "I played yesterday and the day before in a wooden bat league. I am just playing for our high school this summer."
His broken rib forced him to have to have to sit out another opportunity.
"I was going to play for a scout team from the Royals, but it (the injury) set me back a little bit."
With the staggering numbers that he put up this year, and with his ability to play multiple positions, Peavy will be one to watch heading into his senior season. Colleges are just now beginning to take notice.
"I haven't heard from many yet," he said. "I went to Meridian's showcase, and that really has been it. I have been hearing from them. I also have heard a little bit from Southern Miss."
He does have a clear goal in mind.
"My plans are to play at Mississippi State, but I understand that the road there sometimes is through junior college," he said. "So, I'd like to go there (junior college) to get some basic classes out of the way and hopefully get my school paid for. If I am good enough to go anywhere else I'll go, but if I can get some help from baseball for paying for school I will take it."
The focus now for Peavy is solely on baseball.
"I quit some other sports to concentrate on baseball because that is definitely where I have the best chance to make it to the next level."
