The last thing Cal Raleigh needs is more responsibilities. He's already the Seattle Mariners' everyday catcher and their top power threat, and everyone in the organization looks to him for leadership.
Yet because he is indeed the everyday catcher, Raleigh has another responsibility on his plate whether he likes it or not: to challenge or not to challenge close pitches.
Per his past comments, Raleigh is not a fan of the Automated Ball-Strike System that is coming to MLB this year. But if there was any doubt that the ABS system would force him to be hyper-vigilant about being his own judge of balls and strikes, Mariners pitchers hade made it clear they're going to put that all on him.
