San Jose, CA (KSDK)-- After stumbling on her floor routine Friday, St. Louisan Sarah Finnegan has one more chance to impress the judges. Finnegan is right on the bubble of making it to London. And her family says she knows what she needs to do tonight.

Linabelle Finnegan, mother, said, "She was more disappointed in herself when she stumbled on the floor because that's her second best event. But she did 1st in beam, so we still call her the Queen Bee."

Hannah Finnegan, sister, said, "She's kinda a crowd favorite. I like when they clap to her music and her turn, is kind of popular."

Don Finnegan, father, said, "It's actually called a Terin turn. From Terin Humphrey, who was a former Olympian from 2004. And I think she just mastered it very well. She takes it one more turn, I believe, one more turn than Terin did."

Linabelle said, "She's very confident what she needs to do to be there, to London."

Don said, "You clearly want to be in the top 5. An alternate is really good as well. It's an important part of the team. And quite frankly, the coaches can make a decision at the last minute to pull an alternate into the mix, if one of the top 5 is off or it's not working out."

The selection committee will choose 5 women to represent the U.S. in London plus up to 3 alternates. We'll find out at 10 PM CT. Dana Dean for Newschannel 5.
