📣 DAD’S TAKEON MASON BARNETT
Look at this guy winding up like he's trying to flag down a cab in the rain. And what's with that beard? Kid looks like he just rolled out of a tent at a music festival and wandered onto the mound. The A's are really scraping the bottom of the barrel if they're letting guys who look like they should be selling artisanal kombucha throw pitches in the majors.
ABOUT MASON BARNETT
Mason Barnett is a pitcher in the Athletics organization, and honestly he's still working his way up through the system. He's got that classic lefty delivery that scouts love, and Oakland has been patient developing him. Since he doesn't have rookie cards yet, you're mainly looking at prospect cards and minor league issues if you want to get in early. If he breaks through to the majors and sticks, those early parallels and autographs could be solid pickups down the line.
