Toronto Blue Jays top prospect Vladimir Guerrero Jr. keeps on mashing in Triple-A with the Buffalo Bisons, hitting his fourth straight home run.
That of course bodes well for collectors of Guerrero Jr.’s autographed rookie card. The value is already pretty high considering he’s never played a MLB game yet.
But he’s definitely demonstrating his Major League potential.
