On the undercard of BT Sport鈥檚 first live TV bill, James Metcalf halted Jason Ball after five of eight scheduled rounds.

The 28-year-old is keen to establish his own reputation in the game, but comparisons with his famous father, Shea Neary, are difficult to avoid.

Not only are the obvious physical similarities difficult to ignore, stylistically, watching Metcalf you could easily be watching a flashback to the WBU title winning Shamrock Express in his pomp.

Metcalf is also proving to be almost as heavy handed.

His fifth round stoppage of Ball, who campaigns more regularly as a middleweight, took his record to a perfect 15-0, seven now ending early.

Elsewhere on the card, former IBF world champion Paul Butler outclassed Carlos Ruben Dario Ruiz.

If Butler鈥檚 clash with Diaz was a final audition for his right to return to world title company, the Ellesmere Port puncher passed with flying colours.

The Argentinian was described in some quarters as a 鈥済rizzled warlord鈥, but the baby-faced assassin was a class above.

Referee Phil Edwards called a halt to the one-sided clash after just two minutes and 14 seconds of round four and a showdown with Jamie McDonnell moved significantly closer.

Ruiz slipped to 21-10 with 10 now coming before the final bell.
