Updated pre-show odds, 3/15

As we head into this weeks performance show on Wednesday, some interesting things are beginning to shift in our Idol odds. Scott McCreery is beginning to challenge Lauren Alaina as a co-favorite for the title. Nipping at their heels is Pia Toscano, whose back-to-back showstoppers has made a lot of people take notice of her. Falling back are several folks, most notably Jacob Lusk and Thia Megia. Jacob has an unbelievable voice, but his misfire on "I Believe I Can Fly" has chased away some fans. And Thia's poor showing on Michael Jackson's (er, Charlie Chapman's ... uh... Chaplin's) "Smile" has a lot of folks shying away from her as well.

Girls still dominate the bottom of these rankings, as Karen Rodriguez now takes the spot of the one most likely to go home this week. Close behind are Haley Reinhart and Naima Adedapo.
