The Detroit Tigers made a major trade Monday night. They appear to be on the verge of making a major free-agent signing Tuesday.

Free agent closer Joe Nathan will sign a two-year contract with the Detroit Tigers, according to Jon Heyman of CBSSports.com. Ken Rosenthal of Foxsports.com appears to be the first to break the news that the sides were close to a deal.

The Tigers headed into the offseason knowing that they needed to revamp the bullpen and made signing a closer the top priority.

Nathan, 39, would provide the Tigers with a surefire, experienced closer that they did not have on the roster in 2013. He went 6-2 with a 1.39 ERA, 43 saves and a 0.897 WHIP for the Texas Rangers in 2013. Nathan has 341 career saves in 13 seasons with the San Francisco Giants, Minnesota Twins and Rangers.

Joaquin Benoit, last year's closer, is a free agent. The Tigers did not exercise their club option on a contract to bring back Jose Veras next season and will move Drew Smyly to the starting rotation after trading Doug Fister to the Washington Nationals for three players Monday night.
