The first-place Detroit Tigers have reinforced the back end of their shaky bullpen, acquiring closer Joakim Soria from the Texas Rangers for minor-league pitchers Jake Thompson and Corey Knebel.

The trade was completed Wednesday night during Texas’ rain-shortened loss to the New York Yankees. Soria says he was informed of the deal during the delay at Yankee Stadium.

Soria is 1-3 with a 2.70 ERA and 17 saves in 19 chances. Detroit has been looking to upgrade a relief corps that ranked 12th out of 15 American League teams with a 4.37 ERA.

Soria moves from the last-place Rangers to the AL Central-leading Tigers and gets reunited with the closer he replaced in Texas this season. Joe Nathan, a Rangers reliever from 2012-13, has a 5.89 ERA and 20 saves in 25 tries this year for Detroit.
