Minus

Age 38 is a dynasty tax even when 2026 is loud.
Reliever volatility: the ninth can vanish in a week.
Board spread is 78 ranks. You are betting with one camp, not a unanimous tape.
Keep #298 is the edge of the 300. Deep-league / taxi-squad more than a foundation chip.

BaseBallKeep Take

Aroldis Chapman is #298 on BaseBallKeep's overall dynasty 300, a 23-source mix anchored by RotoGraphs (Aug 14) and The Dynasty Guru points list (Aug 10). RP for BOS. Rest-of-season redraft #297. MLB since 2010. From Holguin / Cuba. Bats L, throws L.

BK Value on this rank is 32. Same decaying curve as football: 12,000 at 1.01, a late first a fraction of that. If someone is asking for two firsts, run the calculator. 2026 line: .000 / 0 HR / 0 SB / .000 OPS in 43 games.

The 23-board average is 313.0 on 2 lists that actually ranked him — unranked sources are skipped, never treated as 999. High 274, low 352.

Dynasty pays the next five years. Redraft pays September. If those two ranks diverge, that is the instruction: hold the kid or cash the veteran.

Flags fly forever. We will refresh this file with The Keep. September baseball is a proving ground, not a coronation.
