Alfaro, in his first full season, proved to be a skillful pitch framer and athletic defender, but he needs to make great progress in his pitch blocking and throwing accuracy. He also had the highest strikeout rate in the National League and just a .324 on-base percentage. Alfaro did provide flashes — both at the plate and behind it — of being a legitimate major-league catcher. The Phillies seem to be invested in him. But it would be hard to see him grow if he's buried behind Ramos. And Ramos has little interest in being a backup.
