Rain forces reshuffling of pitching plans

Gorzelanny to follow Dempster Monday against Athletics

MESA, Ariz. -- Rain canceled both of the Cubs' split-squad games on Sunday.

The Cubs were to play host to the Los Angeles Dodgers in Mesa and also travel to Phoenix to face the Chicago White Sox on Sunday. Neither game will be made up.

The Cubs tweaked their pitching for Monday's game against the Oakland Athletics. Ryan Dempster, coming off an 11-9 season and 3.65 ERA last season, will start, his first game in the Cactus League. He will be followed by Tom Gorzelanny, Jeff Samardzija and Sean Marshall. The latter three are competing for the two openings in the Cubs rotation along with veteran Carlos Silva.

"Let these guys compete and let's leave here with the best starting staff that we can," Cubs manager Lou Piniella said. "We have four candidates for two jobs -- we have the two left-handers, Gorzelanny and Marshall, and we have the two right-handers, Samardzija and Silva. Let's leave with the best starting staff that we can and then look at the bullpen."

Mike Fontenot, who has not played for the last three days because of a strained right shoulder, was expected back in the Cubs lineup at second base.
