HOUSTON -- The Rangers are switching the roles of pitchers Phil Klein and Luke Jackson at Triple-A Round Rock. Klein, who has been almost exclusively used in relief in his professional career, is being moved to the rotation. Jackson will go from the rotation to the bullpen.
Klein has a 2.35 ERA in four relief appearances for Round Rock since being optioned by the Rangers on April 14. He has made only two starts in his professional career -- against 123 relief appearances in the Minors and 23 in the Major Leagues.
"The more reps you get, the quicker you can hone your craft," pitching coach Mike Maddux said.
