The Cubs couldn't piece together more than one run in Friday's loss to the Astros in what turned out to be a pitcher's duel.
Ted Lilly, coming off his shortest outing of the season, pitched seven innings. He allowed one run while striking out six.
Jim Edmonds provided the only offense for the Cubs with a solo home run, his 11th of the season.
Carlos Lee tied the game off Lilly in the seventh with his own solo blast into the Crawford boxes in left field.
Hunter Pence drove in Miguel Tejada in the bottom of the ninth inning off Bob Howry.
Howry is taking over closer's duties until Kerry Wood is able to return from a blister on his throwing hand.
The Cubs also placed reliever Jon Lieber on the disabled list with a foot strain. This is the same foot Lieber had surgery on last season.
In a counter move, the Cubs brought up Micah Hoffpauir and are now carrying 12 pitchers instead of 13 but have the extra man on the bench.
The Cubs will send Carlos Zambrano to the hill tonight for Zambrano's first work in the second half.
