[5] At the 2008 Olympics in Beijing, Peszek injured her ankle during warm-ups just minutes before the women's qualification and was able to compete only on the uneven bars.

She placed second on beam and seventh on floor exercise at Nationals[1] and made it to the second and final selection camp for Worlds, but pulled out in order to have the surgical repair performed.

In a tri-meet against Michigan and Utah, she competed in the all-around for the first time since 2012[10] and won with a total score of 39.65 (9.925 on vault, 9.875 on uneven bars, 9.925 on balance beam, and 9.925 on floor exercise).

[11] She then posted a career-high 39.70 all-around score during a tri-meet against Utah State and Bowling Green (9.950 on vault, 9.975 on uneven bars, 9.925 on balance beam, and 9.850 on floor exercise).

She contributed scores of 9.825 on vault, 9.900 on uneven bars, 9.925 on balance beam, and 9.775 on floor exercise to the UCLA team's fourth-place finish.
