American sprinter DeeDee Trotter took her game face to another level Saturday night.

She plans to raise the bar in Sunday's 400-meter final.

"There's an explosion on my face," she says. "Tomorrow I am bringing it bigger, better."

Trotter paints patriotic designs next to her right eye before she competes. In Saturday's semifinals she had a burst of red, white and blue and said it makes her tougher.

"I keep saying it's like that Mike Tyson-type thing. You know when he came back with the tat, he was crazy, crazy maniac," Trotter says. "He just got in there and did whatever it took, and that's the attitude I'm tying to bring tomorrow. My glitter face just showed that: war paint time, time to get the grind on."
