Wilson Ramos had a great offensive year for the Rays in 2018, and many, including me, looked at Mike Zunino as a step down offensively from a guy that was the best hitting catcher in baseball last year.
Prior to joining the Rays, Mike Zunino was a much different hitter than Ramos. Wilson struck out and walked at rates well below league-average while hitting for some power, while Zunino was more of a three-true-outcomes prototype, striking out a lot more than league average, walking at a roughly league-average rate, and hitting for big power.
Here are their BB rates, K rates, OBP, wRC, and ISO relative to a league-average of 100 from 2016-2018, courtesy of FanGraphs.
