Check out these awesome Batman cleats that Lance McCullers, Jr. wore in his major league debut tonight against the Athletics.
This is apparently within MLB rules. Matt Harvey, who has “Dark Knight” carved into his bats, is probably kicking himself for not thinking of this idea first.
As for how McCullers fared on the mound, he allowed one run on three hits and three walks in 4 2/3 innings while striking out five. You can watch video of his first major league strikeout here.
