The website thinks the 16-year-old Sanchez has the best chance of being the next American Idol when the show has its finale June 20, giving her 7-to-4 odds of winning the $1 million recording contract and a car that come with winning American Idol.
In her last performance, Jessica covered Glorida Estefan's rendition of Vicki Sue Robinson's Turn The Beat Around. Contestants had to sing a song released in the year they were born - 1995 in Jessica's case.
Jessica did not exactly wow judges Steven Tyler, Jennifer Lopez and Randy Jackson.
Jackson said the 16-year-old's choice of song was poor, Tyler said it wasn't her best performance and Lopez said Sanchez has to learn to sing straight sometimes.
The Top 10 will perform Billy Joel tunes tonight.
Erica Van Pelt's singing ability is questioned highly by sportsbook.com, which only gives her a 50-to-1 shot of winning American Idol Season 11.
Here are odds for all the final 10 contestants on the show, organized from lowest odds to highest:
Jessica Sanchez: 7 to 4
Phillip Phillips: 3 to 1
Hollie Cavanagh: 4 to 1
Skylar Laine: 5 to 1
Joshua Ledet: 5 to 1
Colton Dixon: 10 to 1
DeAndre Brackensick: 25 to 1
Elise Testone: 30 to 1
Heejun Han: 40 to 1
rika Van Pelt: 50 to 1
