So was Will Middlebrooks at 24. And we got a backup catcher for him, not an ace
At age 24, Middlebrooks had an OPS+ of 102 and Frazier has a 106. I don’t think those 4 percentage points are the difference between ace and backup catcher.
At age 23, Middlebrooks had an OPS+ of 121 in 286 PA, roughly the same as the older Frazier has in 209PA this year. Both players have K/BB concerns and while Middlebrooks is worse, he has a massive defensive advantage over Frazier in terms of position and performance.
Frazier isn’t getting an ace better than Minor, who currently is the ace of a team still in the hunt.
