Daniel Roman was winning entering the 10th round Saturday night, but he left no doubt about his superiority over Gavin McDonnell.

Los Angeles’ Roman knocked down McDonnell in the 10th round of their scheduled 12-round, 122-pound title fight in Chicago and knocked him out. McDonnell made their fight more competitive in the previous two-plus rounds, but Roman hurt him badly with a right hand late in the 10th round and floored him several seconds later.
