Probably. Ortiz was Manny's sparring partner for the Diaz fight. Ortiz was weighing around 152-155 at the time (not training) while Manny was moving up to lightweight from super featherweight.
I think Ortiz would give him a good solid fight. I don't know how his chin would hold up, but, you never know. Freddie Roach was quoted as saying when Ortiz would spar with Pacman, those where the best sparring sessions that he has ever witnessed. then again, its only sparring with head gear and such.
