Aramis Ramirez was injured and Notre Dame Alum Aaron Heilman gave up a 2-run homer to Ryan Braun in the 8th inning as the Cubs blew a 2-0 lead to fall to the Brewers 3-2 Friday in Milwaukee.
Milton Bradley hit a solo home run in the 5th to give the Cubs a 1-0 lead. Chicago added another on a sac fly by Alfonso Soriano in the 6th.
In the bottom half of the 6th, JJ Hardy hit a home run to make it 2-1. Braun then hit the 2-run blast in the 8th for the go-ahead run.
Ramirez went down in the third inning diving for Braun's grounder and immediately clutched his left arm.
The Cubs, who came in winning six of seven, now have yet another injury to add to the growing list of stars who've been out so far this year.
Derrek Lee (neck spasms), Bradley (groin), Soto (shoulder) and Zambrano have all missed time with nagging injuries and Ramirez hurt his left calf earlier this year and sat out six games.
