Watch Sparks fly off catchers mask

According to baseball slang, a pitcher who throws with velocity in the mid to upper 90s is known as a "flamethrower" or a "fireballer." The adjective "blazing" is sometimes used to describe their fastballs, which are a themselves known as "heaters." As in, "Forget about the curve ball Ricky, give 'em the heater."An electrified facemask! Cool! Hey, who says the White Sox can't spark anything this season? Also, it figures that A.J. Pierzynski(notes) would be the guy to do this. He's always rattling cages.STATS LLC, Elias and Fangraphs all report that the majors have not experienced sparks since knuckleballer Steve Sparks retired after the 2004 season.The pitch in question was an 0-2 fastball from relief pitcher Joaquin Benoit to White Sox catcher A.J. Pierzynski that Pierzynski fouled straight back into Avila's mask. It is unclear whether the ball hitting the mask or the ball forcing to parts of the mask to rub caused the sparks to fly.
