Zambrano to make start Friday

Carlos Zambrano will make his return to the Chicago Cubs' starting rotation on Friday in Houston against the Astros, the team announced.

The right-hander, who was sent to the bullpen on April 24, was scheduled to start Wednesday in Pittsburgh, but the game against the Pirates was rained out and will be made up Monday.

Zambrano has not started a game since April 20. He went 0-1 with a 4.15 ERA in 13 relief appearances, and he's a combined 1-3 with a 6. 12 ERA on the season.
