Manny Pacquiao is the hands-down favorite to beat mixed martial arts expert Korean DK Yoo in their six-round exhibition bout this Sunday at the KINTEX in Goyang, Korea.

Oddsmakers have installed Pacquiao at -900 and Yoo at +700. Given that the fight is set for just six rounds, a draw is listed at +1000.

Those who prefer putting money on the Filipino eight-division champion will have to fork out $900 just to win $100 while those who root for the underdog Yoo will make a killing if he wins since a mere $100 wager will win $700.

If a bettor picks a draw, his $100 will win $1,000.

The overwhelming odds is not surprising given Pacquiao's lofty stature and Yoo's mysterious but intriguing background.

Pacquiao is not taking Yoo lightly that he spent two months training in General Santos City.

Yoo, who is a bit younger at 42, even worked out at the Wild Card Boxing Club in Hollywood before spending the entire camp in Korea under a former Korean world champion.

At the Wild Card, Yoo even did pad work with Filipino cornerman Marvin Somodio, who is Freddie Roach's able assistant.

Somodio swears Yoo, despite his lack of solid background in boxing, shouldn't be dismissed.

Yoo is not only taller and bigger, Somodio said, he is also very strong.

The Yoo showdown will be Pacquiao's first ring appearance since losing to Cuban counter-puncher  Yordenis Ugas in Las Vegas 16 months ago.

Pacquiao and his team arrived in Seoul last Monday.
