DENVER (AP) -- Jamar Beasley scored in the 40th minute as the Chicago Fire rallied to tie the Colorado Rapids 1-1 in 100-degree heat Saturday.

Colorado's Marcelo Balboa opened the scoring in the 7th minute with a header off a pass from midfielder Imad Baba. Chicago goalkeeper Zach Thornton could not reach the shot just inside the left post.

Beasley took advantage of a Rapids' miscommunication in the 40th minute. Colorado, thinking the play was offside, left Beasley wide open. He accepted a pass from Dema Kovalenko and scored past Colorado goalkeeper Scott Garlick.

Both teams had scoring chances late in the game and in overtime, but were clearly slowed by the stifling heat.

Chicago (11-5-4) played in its eighth overtime game. Colorado (5-9-7) has played in seven overtime games, and all have ended in ties.
