Fantasy baseball managers should consider moving Aroldis Chapman before the Boston Red Sox potentially do. Despite a 2.36 ERA and 18 saves this season, Chapman's role could be in flux given the Red Sox's last-place standing and his limited innings pitched (only 26 2/3). Chapman, who will be a free agent after the season, has allowed runs in four of his last seven appearances, a concerning trend for fantasy managers prioritizing saves. The Red Sox, with an August 3 trade deadline looming, might explore moving the veteran left-hander to a contender, potentially shifting their closer role internally or trading him altogether.

Other closers facing potential trade deadline movement include Josh Hader of the Houston Astros, who has shown strong form with 24 strikeouts in 15 innings since returning from injury, and Pete Fairbanks of the Miami Marlins. The article also highlights potential beneficiaries of closer changes. Tyler Wells of the Baltimore Orioles is positioned to maintain the closer role while Ryan Helsley recovers from elbow issues, and Jacob Webb of the Chicago Cubs could also see save opportunities with Daniel Palencia sidelined.

Conversely, fantasy managers might want to reassess their holdings in Paul Sewald of the Arizona Diamondbacks. While Sewald boasts 20 saves, he has surrendered three home runs in his last six outings and seven overall, leading to a 4.50 ERA. Despite a strong WHIP, the increased long-ball susceptibility could lead the Diamondbacks to consider other options. Similarly, Gregory Soto of the Pittsburgh Pirates has allowed home runs in three of his last four appearances, raising questions about his long-term grip on the closer role, even if he is still expected to get save opportunities.
