Vladimir Guerrero Jr. Snaps Bat Into Pieces After Strikeout

Vladimir Guerrero Jr. just did his best Bo Jackson impression ... completely -- and easily -- destroying his bat over his leg following a tough strikeout.

The Toronto superstar turned his personalized lumber into kindling in the fifth inning of the Blue Jays' game against the Yankees ... when he struck out on a Jameson Taillon cutter.

Guerrero Jr. was so mad at himself for waving at a pitch that ended up outside of the zone -- he slammed his bat to the ground ... and then snapped it over his right quad.

Video shows the thing didn't stand a chance against the wrath of the 6'2, 235-pound first baseman ... it splintered all over the batter's box.

If you're wondering, there's no MLB rule against snapping a bat in frustration ... so Vladdy won't face any penalty over the temper tantrum.

As for the game ... the Jays are currently down 5-2 -- but Vlad's gotten another bat and is scheduled to come up again shortly.
