The move comes days after Boston signed lefty reliever Danny Columbe to a big league deal. The contract for Kahnle should give the Red Sox more depth in the bullpen. <\/p>\n

Thanks in large part to an All-Star season from Aroldis Chapman, the Red Sox ranked second in MLB \u2014 and tops in the American League \u2014 in reliever ERA (3.41) and ninth in WHIP (1.25).<\/p>\n
Kahnle, 36, pitched last season with the Tigers, holding a 4.43 ERA and 1.302 WHIP across 66 appearances. He also saved nine games for Detroit, which made the playoffs as a wild-card entrant. He was mostly undone by an ugly July in which he carried a 19.64 ERA across 11 games.<\/p>\n
Most of his innings, 195 2\/3 to be exact, came over six seasons and two separate stints for the Yankees. He was first acquired by New York in a pre-trade deadline deal with the Rockies in 2017. <\/p>\n
His best season in The Bronx came during his last in 2024, when he recorded a career-best 2.11 ERA over 42 2\/3 innings.<\/p>\n
Kahle didn\u2019t allow a single earned run through his first eight playoff games in 2024 but allowed two without recording an out in Game 5 of the Fall Classic, taking the loss as the Dodgers took the series.<\/p>\n

He\u2019s known for wielding his changeup as his primary \u2014 and sometimes only \u2014 offering, and he deployed it at an 86 percent clip in 2025.<\/p>\n
Kahnle also pitched two scoreless innings for Team Israel at this year\u2019s World Baseball Classic.<\/p>\n","protected":false},"excerpt":{"rendered":"One former Yankee is heading to the Bronx Bombers\u2019 biggest rival.
