Major League Baseball has told teams that it’s OK for pitchers to use the kind of scouting cards that umpire Joe West confiscated from Philadelphia reliever Austin Davis on the mound this weekend.

Phillies manager Gabe Kapler said Sunday that he’d been informed the cards were legal. They are, provided they don’t delay games, MLB told clubs in clarifying the policy.

It has become common in the age of advanced baseball analytics to see outfielders and infielders pulling info cards from their pockets to check on proper positioning.

I’m into the analytics of baseball and I think it’s great to study who you’re facing. However, pitchers having cheat sheets on the batter takes away from the game, and probably just another thing that will slow down the game.
