This is great news. I was more than certain that the show was getting axed, especially with the American Dad renewal. With a short order (no pun intended) of 13 episodes, I'd expect to see this come back next Spring, once they're run through the gamut of AD/Cleveland episodes early in the fall.
If you got turned off by the admittedly-awful first episode, give it another chance. You won't be sorry.
I take the opposite tack - the freestyle was the highlight of the show for me, and there wasn't much of anything to write home about otherwise. ("Needs more Tim," maybe?) The Cleveland Show 1x5 "Cleveland Junior's Cherry Bomb"
