The Tigers have acquired closer Joakim Soria from the Rangers in exchange for right-handed pitching prospects Jake Thompson and Corey Knebel, Detroit announced on Wednesday night. The deal was first reported by Kyle Bogenschutz of and Jon Morosi of Soria will likely assume the closer role for the Tigers, who entered the day with the fourth-worst bullpen ERA in the American League with a 4.41 mark. Detroit has been pursuing bullpen pieces like Soria and Jonathan Papelbon of the Phillies for a couple of weeks, and will receive a back-end upgrade from the Rangers when the deal becomes official. Soria, 30, has pitched to a 2.70 ERA and earned 17 saves in 33.1 innings in his first full season since 2011. He took over the closer role in Texas in place of Joe Nathan, who coincidentally signed with the Tigers last offseason and now will be teammates with Soria once again. Nathan's struggles (5.89 ERA in 39 appearances) are one of the main reasons that the Tigers needed to acquire a bullpen arm like Soria.
