Aroldis Chapman, with 339 career saves, is closing in on Rollie Fingers' record. His performance as a veteran closer has been a guiding influence for the younger Justin Slaten. Chapman praises Slaten's strong command and velocity, indicating he believes the latter has a bright future as a closer.

Chapman hit 103.4 mph with his fastball, showing impressive velocity and control, which has improved since past seasons. His ability to minimize walks has been a significant factor in his effectiveness this year.

Aroldis Chapman remains the primary option for saves on the Boston Red Sox. His experience and effectiveness in high-leverage situations keep him at the forefront, despite sharing some save opportunities.

Aroldis Chapman has made an early impact for the Red Sox as one of the few pitchers to earn both wins and saves this season. Despite his inconsistent outings, his strikeout potential and ability to find save opportunities make him a valuable fantasy asset.

Chapman has emerged as the clear favorite to close for the Red Sox, especially with Liam Hendriks sidelined. His performance post-All-Star break last year suggests he could have top-10 fantasy closer upside.
