His ERA, FIP and xFIP have all been above 4 the last two years. This year the sample is small thus far but both his FIP and xFIP are worse than Duffey’s I think they are generally considered to be better predictors of future performance.
I don’t think he will perform worse than Duffey but I am clouded by the small sample of performance. I think the lack of confidence in Pagán is entirely because he hasn’t pitched well since 2019. Even in 2019 his LOB% was 94.8. This year it is 94.7. That really isn’t a skill. His career rate is near the league rate this year of 75. Can we really count on him to have an LOB% of 95% going forward?
