Mayweather-McGregor: Savannah Marshall starts pro career with win in Las Vegas

Savannah Marshall thunders a right into the head of Sydney LeBlanc

The Hartlepool boxer, signed this summer by Mayweather Promotions, opened the show which is being headlined by her boss, in some style.

Marshall launched the Floyd Mayweather-Conor McGregor undercard by subduing the tough American, LeBlanc, who came into the four-rounder with a winning record.

But the confident Headland star controlled proceedings from the first bell at the T Mobile Arena.

LeBlanc, from Louisiana came into the bout having taken world champion, Claressa Shields the full eight rounds in May, but Marshall made sure the 33-year-old never got a foothold in the bout.

The 26-year-old used her footwork superbly, boxing confidently behind her jab, taking the contest to LeBlanc.

Marshall forced her opponent onto the ropes, where Sydney successfully covered up.

The former world champion maintained the pattern in round two and jolted her rival's head back in the third though it only sparked some action from the girl from the States.

Marshall, who had Headland coach Tim Coulter in her corner, though was soon on the front foot again, forcing the pace and forcing LeBlanc on the retreat.

All three judges scored it for the girl from Dyke House as she began her new career in emphatic fashion.
