10-9 Penn, 10-9 Fitch, 10-8 Fitch.
The second round was close but I thought it was Fitch's for sure. I don't think Penn was "threatening" Fitch at all in the very brief time he had his back. I don't think having someone's back is automatically threatening and BJ was never close to a sub. Fitch got some pretty decent GnP even in the second, people say he does nothing but he was landing some decent shots when he was on top.
I don't know how the third can be anything but 10-8, BJ did absolutely nothing for the entire round while Fitch pounded on him.
