Dunning (ankle) allowed two runs on three hits and one walk while striking out nine over five innings Thursday for the Rangers' rookie-level Arizona Complex League affiliate.
The Rangers are already listing Dunning as their probable starter for Tuesday's game at Seattle, so it looks like he'll be activated off the 15-day injured list that day if he comes out of this rehab outing without any setbacks. The fact that the right-hander was able to throw five innings Thursday suggests he'll be ready to handle a normal workload in his return to the Texas rotation.
