Frankowski's late goal lifts Fire to 1-1 tie with Crew
Nikolic Nemanja, at the top of the 6-yard box, redirected a low cross by Aleksandar Katai and Frankowski side-netted a first-timer to tie it in the fourth minute of injury time.
Kenneth Kronholm had six saves for Chicago (8-12-10).
Pedro Santos took a pass near midfield, raced down the right flank and cut back to evade a defender before blasting a low left-footer inside the far post from well outside the box to give the Crew a 1-0 lead in the 27th minute.
Columbus (8-15-7) has just one loss since losing 1-0 to Orlando City on July 13. Eloy Room, a 30-year old who signed with the Crew on July 5, had five saves.
