"The velocity will come when it comes," Harrison said. "I wanted to maintain my velocity, which I did. I think my stuff was sharper than it had been in a long time."
Pitching coach Mike Maddux said the Rangers aren't sure if Harrison will pitch again in Arizona or go on a medical rehab assignment in the Minor Leagues. The Rangers want to be sure he is ready because the rehab assignment has a 30-day time limit.
Harrison, who has made just six starts in his past two seasons, underwent spinal fusion surgery June 3, 2014. There is no history of a pitcher returning from such a serious operation, but Harrison is starting to chart a course.
