EDGE Analysis

Chapman has been among the most dominant closers in MLB this season, posting a 1.04 ERA, 0.67 WHIP and 74:14 K:BB over 52 innings spanning 57 outings while racking up 26 saves in 28 chances. The 37-year-old joined Boston on a one-year contract last December and will now be with the club for at least one additional campaign. Romero explains that the option for 2027 is a vesting option that will become a mutual option if it doesn't trigger.
