Chapman, 37, blends elite velocity with masterful off-speed placement, turning a storied career into a season of late-career peak for Boston. A four-strikeout ninth against Arizona capped a run in which he has not allowed a hit in 14 2/3 innings over 17 outings, dropping his ERA to 0.98. The outing sealed a milestone win for Cora and reinforced Chapman’s fantasy upside as a premier closer for the stretch run.
