"Dancing with the Stars": Hope Solo is out of hope

Martinez and Lake have been leading the charge, but Kardashian has made a surprising comeback, so he's not out of the game yet.

On Monday, as part of the freestyle competition, contestants will choose their own dance in hopes of winning the mirror ball trophy.

"If they get that wrong, they're not going to win, that's for sure," "DWTS" judge Bruno Tonioli told ABC.

So who will win the ballroom competition?

According to online betting site, Martinez has the edge: He's favored with 1/2 odds, followed by Ricki Lake (3/1) and Rob Kardashian (4/1).

But Martinez recently suffered a twisted ankle, and it has already impacted his performances. "That is a major handicap," said Tonioli. "So, hopefully, he'll be able to do his best, you know. I don't know."

The contestants, who have been rehearsing the past week, hinted about their upcoming performances but didn't give too much away.

Lake, who's partnered with three-time champion Derek Hough, said her dance will be upbeat, adding, "But I couldn't even tell you what style of dance it is because I'm not a dancer."

Kardashian said his partner Cheryl Burke will choreograph a routine that fits his personality -- probably "old soul," he said.

And then there's Martinez, who said he's going to be "fearless" Monday night. "I'm going to be a risk-taker," said Martinez who dances with Karina Smirnoff. "Because I want the ballroom judges to be like, 'Wow!'"

The winner will be determined by a mix of judges' scores and viewers' votes.

The "DWTS" finals get underway Monday night at 8/7 C on ABC.
