Carpenter had his contract selected from Triple-A Nashville on Tuesday, Evan Grant of The Dallas Morning News reports.
EDGE Analysis
Carpenter was designated for assignment by the Rangers on June 8, but he'll be added to both the 40-man and 25-man roster following Tuesday's move. He's made just one appearance in the majors this season, yielding two runs over 0.2 innings of work. The right-hander will take the place of Jesse Chavez, who was sent to the 10-day injured list Tuesday with a right elbow impingement.
