Per SNY MLB Insider Andy Martino, the two-year contract will pay the right-hander $11.5 million. Ken Rosenthal of The Athletic was the first to report the deal.
Kahnle, 33, previously spent parts of four seasons with the Yankees, who acquired him in a 2017 trade with the White Sox that also brought David Robertson and Todd Frazier to the Bronx.
In 129 regular season appearances as a Yankee, Kahnle pitched to a 4.01 ERA with 12.6 Ks per nine innings. His best work in pinstripes came in 2017, when he pitched to a 2.70 ERA in 32 games with New York.
Health has been a major factor for Kahnle, who pitched just one game in 2020 before needing Tommy John surgery, which forced him to miss the entire 2021 season as well. He returned to pitch just 13 games for the Dodgers in 2022, as forearm inflammation took away a large chunk of his season.
The veteran right-hander had pitched parts of eight seasons in the bigs with the Yankees, Rockies, White Sox and Dodgers.
