It looks like the Tigers will get Joakim Soria from the Rangers:

Soria was throwing stellar innings for Texas, having yet to allow a home run.

Corey Knebel strikes out a ton of batters, but at age 22 has yet to develop control. Jake Thompson is a 20-year-old starter who puts up good numbers in A ball. Looks like the Rangers get two potentially good pitchers for a reliever.
