Glasgow - It wasn't pretty, and local crowd acknowledged it by booing the final verdict, as Zach Parker (17-0, 11 KOs) was getting strapped with the Lonsdale belt following his close win over Darryll Williams on a disputed split decision.

It was a match-up between two unbeatens: a predator (although with a long tooth) in Williams, and a trickster (with a solid punch though) in Parker. Williams, using Tysonesque peek-a-boo style to get inside Parker's fire range, tried to deliver one solid shot. He was successful on multiple occasions, using his left to not only rub his opponent's nose but also to trouble him several times. Parker, on the other hand, moved well laterally, popped his jab into Williams' face and held on if necessary.

After twelve competitive rounds, many felt that more aggressive fighter deserved to have his hand lifted, as he also had less marks on his face than fellow undefeated.

Yet, while one of the judges had it 115-113 - for him, the other two favoured Parker as the new BBBofC British super middleweight champion with scores 117-112 and 115-114. Williams is now 17-1, 7 KOs.

Paul Butler got back to winning ways on Saturday.

The former IBF bantamweight world champion had been out of the ring since losing at the hands of Emmanuel Rodriguez back in May.

Butler, however, advanced to the reserve position for the semi-finals of the World Boxing Super Series with a victory over Yoan Boyeaux.

He was added to the card at late notice but, after a win in the quarter-finals over the Frenchman over 10 rounds at the SSE Hydro in Glasgow, exclusively live on iFL TV in the UK and DAZN Stateside, Butler will now wait for his next lot of action after failing to land the showdown with Ryan Burnett for the WBA Super and vacant WBC Diamond bantamweight title after Nonito Donaire successfully made the 118-pound limit.

The scorecards on the supporting cast of Josh Taylor’s WBC Silver super-lightweight title defence against Ryan Martin were quite straightforward as the scoring adjudicator, referee Kenny Pringle, handed it to the Ellesmere Port man by 99 points to 91.

Meanwhile, in the reserve bout at super-lightweight, Viktor Postol was taken the distance by MTK Global fighter Siar Ozgul. But ‘The Iceman’, who was last in action against Josh Taylor back in June, won all but one round, with the scores being 99 points to 91.

And Stephen Tiffney got the better of Arturo Lopez, despite getting dropped, in a six-round contest, getting the nod on the scorecards by 58 points to 55.
