Scouting Report: Aroldis Chapman

Summary

Aroldis Chapman, 38-year-old left-handed closer for the Boston Red Sox, is experiencing a career renaissance in 2026. Chapman has converted all save opportunities (11+ saves) with an exceptional 0.54-0.71 ERA and 0.72-0.88 WHIP. He has recorded 23 consecutive save conversions dating back to July 2025, with opposing hitters batting just .123 against him in that stretch with 41 strikeouts. Chapman is approaching several all-time records: 378 career saves (10th all-time, 12 away from tying Dennis Eckersley for 9th), and needs only 17 more strikeouts to set the career record for relief pitcher strikeouts. He has maintained a 10-game scoreless streak and continues to be nearly untouchable with elite strikeout rates (12.3-12.5 K/9). The Red Sox's signing of Chapman on a one-year deal has proven to be one of the best moves by the organization under Chief Baseball Officer Craig Breslow.
