RIO DE JANEIRO -- American boxer Claressa Shields is one win away from a second gold medal.

Shields danced her way out of the ring following a unanimous decision victory over Kazakhstan's Dariga Shakimova in a middleweight bout.

She won 40-36, 40-36 and 39-37 on the scorecards on Friday.

Shields will add to her tattoo collection with a win in the gold medal bout. She has the Olympic rings tattooed on her right bicep. "Rio" and "London" are inscribed within the bottom two loops.

She said she would get an "Au" tattoo because those letters on the periodic table stands for gold.

The 21-year-old Flint, Michigan native hasn't lost a fight since the London Games, winning two world championships and a Pan-Am Games title between Olympics.
