What happened: An impending transaction threatens the fantasy baseball value of Aroldis Chapman. Joining a playoff-bound roster could relegate the left-hander to an eighth-inning setup position rather than finishing games.

Why it matters: Industry analysts assign a high probability to a deal involving the Boston veteran, with the Los Angeles Dodgers linked as a frequent suitor. Any shift in usage introduces immediate volatility for managers currently benefiting from his consistent ninth-inning production.

What to watch: Observers will track the August 3 trade deadline to monitor his ultimate destination and new bullpen hierarchy.
