CHICAGO -- Most of Brian Giles' plate appearances have come near or at the top of the Padres' batting order.

In an effort to ignite Giles' slumping bat, manager Bud Black moved him down to No. 7 against Cubs left-hander Ted Lilly on Wednesday.

Giles, who led off as recently as Tuesday night and usually hits third, had not been penciled in as low as seventh since 1998, when he was 27 years old and finishing his third full season in the Majors with the Indians.

"Just trying to give Brian a different perspective on it," Black said. "Lilly's tough on left-handed hitters, and that's really about it."

Giles came in batting .161 with minimal power in 124 at-bats, and he is 2-for-14 on the Padres' road trip. He's not the only player not hitting, but the offense won't reach its potential, Black said, with Giles struggling.

"He's the one guy -- well, I don't want to single him out -- but for us to get it going offensively, we need our entire lineup to get back to their level, to get back to their norm," Black said.

Giles is a career .292 hitter with a .906 OPS -- on-base plus slugging percentage -- who hit .306 with 40 doubles in 2008.

"Brian's pressing a little bit," Black said. "A lot of times you become impatient because of an anxiousness to get out of a funk. You want it to happen yesterday. It's tough."

Adrian Gonzalez hit third and Chase Headley hit cleanup.
