The Tigers have acquired right-hander Francisco Rodriguez from the Milwaukee Brewers in their latest attempt to stabilize the back end of their bullpen.
The teams announced the trade Wednesday. Milwaukee receives minor league infielder Javier Betancourt and a player to be named.
Rodriguez, who turns 34 in January, went 1-3 with a 2.21 ERA for the Brewers in 2015. He had 38 saves in 40 chances.
Detroit's bullpen has been an issue for the last few seasons. The Tigers this month declined their $10 million option on Joe Nathan. He spent two years with Detroit, struggling in 2014 and missing almost all of 2015 with an elbow injury.
Detroit finished last in the AL Central this year after winning four straight division titles.
