MLB.com's Mayo: 'Maybe the best all-around catching prospect in this class' 5:09 AM UTC Share share-square-557827 When the Marlins scouted prep catcher Joe Mack, they saw him compete in three sports: basketball, volleyball and baseball. In one particular instance, director of amateur scouting DJ Svihlik returned to upstate New York and caught him taking batting practice the morning after a district championship volleyball match. "It's very impressive when young players will do that, and you can't understate how important it is that they are playing multiple sports," Svihlik said. "That plays into the fact that he hasn't played as much as some other guys, and then to go out last summer and to perform like he did on the biggest stage and be as competitive and successful, that gives you a lot of comfort that you got a player that just [not only has] tools, but he can actually play the game. So I was really excited."
