LAS VEGAS – Brian Norman and Quinton Randall wrestled more than they boxed Thursday night.

When their dull 10-round welterweight bout mercifully came to a conclusion, all three judges concluded that a more aggressive Norman had done enough to win their bout on the Shakur Stevenson-Edwin De Los Santos undercard at T-Mobile Arena. Eric Cheek (99-91) and Steve Weisfeld (99-91) scored nine apiece for Norman, who remained unbeaten but didn’t impress in his third fight since he signed a promotional contract with Bob Arum’s Top Rank Inc.

Judge David Sutherland scored seven rounds for Norman, who won 97-93 on his card.

Randall (13-1-1, 3 KOs), of Katy, Texas, was the first undefeated fighter Norman fought during his five-year pro career. The 22-year-old Norman (25-0, 19 KOs), who has a reputation as a puncher, has gone the distance in each of his three fights since Top Rank signed him to a promotional contract last December.

The Conyers, Georgia native had surgery on his right hand in June, which he expected to lead to an impressive performance in his first fight back from it Thursday night.

Randall initiated a lot of the clinches as Norman pressed forward throughout their bout.

For the first time in several rounds, Norman nailed Randall with a short left on the inside a little less than 50 seconds into the 10th and final round. They went back to jostling for position soon thereafter and didn’t do much until the final bell rang.
