The Mariners' High-A affiliate hosted Education Day at Funko Field on Thursday afternoon, packing the Everett AquaSox park with youngsters. While classroom subjects got much love, those in attendance also got to experience a one-of-a-kind tutorial in Bat Flip 101 with Seattle prospect Michael Arroyo serving as the professor.

There are bat flips, and then there are bat flips. And then there's whatever it is Boston Red Sox prospect Andy Lugo did on Saturday. Look at this. That bat couldn't be much higher in the sky without a full-on windup.
