Now obviously, we aren’t going to crown Mariners catcher Omar Narvaez the best catcher in team history. He’s only played 41 games and Dan Wilson and Mike Zunino are still quite a ways ahead of him.
But in those 41 games, Narvaez is doing serious damage. He is slashing .307/.377/.511 with 8 home runs and 15 walks. His 143 wRC+ ranks fourth amongst all catchers, as does his .511 slugging percentage and his .377 OBP.
But how does this stack up against the best seasons of Mariners catchers? If the season ended today, Narvez would be the single-season leader for batting average, second in OBP, and first in slugging.
