In this episode of Bucco Bantr, we sit down with Pirates reliever Isaac Mattson to recap his stellar 2025 season. We talk about his dominant stretch on the mound, the confidence behind throwing his fastball nearly 80% of the time, and how his mentality and emotion fuel his success in high-leverage spots. Isaac reflects on the growth he’s made this year, the trust he’s earned in the bullpen, and what drives him every time he takes the ball.

A great mix of insight, intensity, and personality — this is one you won’t want to miss.
