The Rangers activated Harrison (back) from the disabled list Saturday. Harrison will not get into a game until he starts Tuesday, but the Rangers were forced to make a roster move with him reaching the 30-day maximum on his rehab assignment. Harrison was not particularly sharp during his minor league stint, posting a 6.23 ERA and 21:15 K:BB ratio over six rehab starts, so he will likely have to sharpen things up to hold down a spot in the Rangers' rotation.
