Mastros oozes physicality in the batter’s box, largely in part to a powerful 6-foot-2, 225-pound frame. He made plenty of loud contact throughout the PBR at The Rock Fall Championships and worked comfortably to all fields, hammering one to his pull-side on Saturday for a single and following it up with a triple into the right-center gap in the next at-bat. There’s plenty to like here from an offensive standpoint and he certainly profiles as a middle-of-the-order type thumper at the next level.
