CHICAGO (AP) -- The big matchup between Big Z and the Big Unit never materialized.

Pinch-hitter Daryle Ward delivered a two-run double in the eighth inning, and the Chicago Cubs rallied again to beat the Arizona Diamondbacks 6-4 Sunday after the anticipated showdown between Carlos Zambrano and Randy Johnson got wiped out.

Carlos Marmol (1-0) struck out two in a perfect eighth and Kerry Wood pitched the ninth to earn his seventh save in 10 chances and finish off Chicago's three-game sweep of the NL West leaders.
