Three Zips have already advanced to the finals, GoZips.com confirms. Three more still have to compete.
Tomasz Smialek (men's high jump), John Russell (men's pole vault) and Ashley Kaufman (women's javelin) will compete in the finals on Friday. Natalie Sako (women's high jump), Auston Papay (men's discus) and Randall Hafner (men's discus) are still wrapping up their events.
I will update you once I know more.
