The Boston Red Sox agreed to a contract extension with left-hander Aroldis Chapman, per multiple reports.

The deal contains $13.3 million in guarantees, according to MassLive. He will be under contract for next season and carry an option for 2027.

Chapman, an eight-time All-Star, has posted career-lows in ERA (1.04) and WHIP (0.673) in 57 relief appearances this season, his first with Boston, which signed him to a one-year, $10.75 million contract in December. In addition, he has racked up 26 saves and 74 strikeouts with 14 walks in 52 innings.

The 37-year-old has a career 2.53 ERA in 853 appearances.

Chapman is 13th on the all-time career saves list (361); he is only 17 saves away from passing Joe Nathan and moving into the top 10.

The Red Sox are in the midst of a successful regular season. They currently have a 75-62 record and occupy the second wild card spot in the American League.
