KANSAS CITY -- Matt Harrison, on the disabled list with biceps tendinitis, is scheduled to pitch two innings on medical rehabilitation assignment for Double-A Frisco Wednesday night. If all goes well, Harrison will join the Rangers in Minnesota and be activated either Friday or Saturday.
He will replace Guillermo Moscoso in the bullpen. The Rangers will use him as both a long/middle reliever, and as a possible left-handed situational reliever in the sixth and seventh innings.
"We think where he fits best right now," Rangers manager Ron Washington said. "He gives us a second lefty with length and a guy who we can use more than one inning."
The Rangers also hope Harrison can take some of the workload off Darren Oliver, who entered Wednesday with 22 appearances, tied for the sixth most in the American League.
