Prince Fielder's Age-Arc
As Bill James put it, age-arc projection for batters is basically a simple thing. Past age 30, they are skiing down a slope towards replacement level, and how long it takes them is merely a function of how high up the slope they are when they start.
- Fielder's age-arc projection is more complicated than for most hitters, in my view:
- He'll only be 28 (!) at the start of his contract -- won't turn 28 until next May.
- His top eight B-Ref comps averaged 10 years of cleanup hitting from here.
- Out-of-shape hitters DO seem to age quicker: Luzinski, Dunn, Hrbek, Cecil Fielder, Mo Vaughn, Boog Powell.
Adam Dunn, if this be his crash year (?!) hit it at age 31, but I doubt that it is. Anyway, he'd be quite an outlier in this group; the comps include Eddie Murray who had 15 ! years left at age 27, Strawberry, Will Clark, Juan Gonzalez, etc.
