Cubs to switch up top of lineup

CHICAGO -- A sixth consecutive defeat, a sweep by the crosstown Chicago White Sox and the first shutout of the season all have Chicago Cubs manager Dale Sveum working on the details of a lineup change for his last-place club.

Sveum didn't reveal too much after Sunday's 6-0 defeat other than saying that changes are expected to happen to the top three spots in the order. That's where David DeJesus, Tony Campana and Starlin Castro have resided most of the season, in that order.

"I'm thinking about changing things at the top of the order there, not that anybody is doing anything wrong, just to change something," said Sveum, whose team opens a three-game series at Houston on Monday. "We aren't producing any runs that way. We might change things up there."

Before the Cubs were shut out Sunday they were 12th in the 16-team National League in runs scored with 149.

DeJesus, whose .360 on-base percentage is second only to Bryan LaHair's .415 mark, had been on a tear with a 10-game hitting streak, but saw that come to an end when he went 0 for 5 on Sunday. Over his previous 15 games he was batting .350.

Campana, who put a spark into the lineup when he was recalled in April, went just 2 for 12 on the homestand with one run and one steal.

Castro, who leads the team with 25 RBIs, was just 3 for 18 on the homestand, but did have some good at-bats Sunday. Castro entered play tied with Boston's Mike Aviles for the most RBIs from a major league infielder. Despite the shutout, Castro has driven in a run in five of his last eight games.

Sveum's changes could have Alfonso Soriano or LaHair taking over the No. 3 spot. Despite a sore knee that has hampered his running, Soriano is hitting .311 (19 for 61) with six doubles, three home runs and 11 RBIs in 16 games this month.

"He's the manager and I think he wants to make the team better and help the team to make a better lineup to score some runs," Soriano said.
