Matt Harrison (back) wasn't pleased with Monday's rehab start at Double-A Frisco in which he allowed three runs -- two earned -- on six hits and three walks over 3 1/3 frames. The left-hander needed 77 pitches to get through the 3 1/3 innings. The good news is that Harrison didn't have a setback physically and remains on track to return around the end of the month. He'll be on a 95-pitch limit for Saturday's start in Frisco.
