Acknowledging that there is a difference between carrying and taking your time, Orlando Canizalez carried Bones Adams.
It's pretty obvious even from the archaic film that Jack Johnson carried Tommy Burns. You could see him literally pulling Tommy up around the armpits and toying with him.
Stanley Ketchel is another one that was carried by Johnson. It's funny to see how in some moments of the fight he's literally lifted off the floor by Johnson.
Ali carried Coopmans for a couple of rounds.I don't believe he carried Mildenberger, I just think he found his southpaw style puzzling ,he hadn't fought one since the amateurs
After seven rounds his corner suggested that he close the show but he said, I haven't finished punishing for all the mouthing off he did earlier.
I don't know if he so much carried these fighters as much as he just didn't do a thing with them for several rounds and then just turned it on when he wanted to go home. And that was Ali against Folley, the second fight with Patterson and Jurgen Blin. Come to think of it, that probably is the definition of carrying, but like Greynotsoold said, maybe it's just taking your time. Oh, and one more I just thought of. Henry Armstrong carried Barney Ross to the finish line. I knew Davey Day, Ross' stablemate and he corroborated that their mgmt. asked Armstrong's braintrust to let him make it to the end.
