Simone Biles performance at  U.S. Gymnastics Championships

She competed all four events on Friday, vault, uneven bars, balance beam, and floor exercise.

Her highest score came on vault, where she scored a 15.200

She also scored 14.350 on floor exercise, 14.000 on uneven bars, and 13.750 on balance beam.

Her total score of 59.300 was more than 2.5 points ahead of second-place Shilese Jones.

Biles' performance was impressive and showed that she is still the best gymnast in the world.

She is the clear favorite to win the all-around title on Sunday.

If she wins, she will break the record for most national all-around titles, which is currently held by her at seven.

She will also be the oldest woman to win the championships, at the age of 26.
