Earlier this season we caught up with Burleson and asked him about his motivation this season.

“I’ve always had to prove myself a lot through life in baseball. And I feel that’s what’s pushing me to keep going. To prove myself that I belong here. And the next level and the next level and whatever that may be. I’ve put a lot of time into it throughout the years. And my parents are always pushing me. Family is big for me. They’re pushing me. They always want to talk baseball. And pushing me to be better,” said Burleson.
