Even after the league's requirements changed, the future Hall of Famer was still able to utilise it since it was grandfathered in.

Before the World Series began, Martin Maldonado of the Houston Astros requested that Pujols bring him several bats.

In Game 1, he utilised the slugger's model, which was later shown to be an illegal bat.

Early in Game 2 on Saturday night, FOX aired a brief, 50-second feature on Maldonado and the bats he used in Games 1 and 2.

He learned today from MLB that the bat he used last night wasn't an authorised one.

He selected a model that he had gotten from Albert Pujols because he believed it to be quite comparable to his own model.
