Extra bases

• Catcher Steve Clevenger, on the disabled list with a left oblique strain, has been playing games in Mesa, Ariz., at the Cubs' facility.

"He's been abusing some of our guys when he's playing in intrasquad [games]," Hoyer said Monday.

Camp, on the disabled list with a sprained right big toe, is still resting and not ready to resume baseball activities.

• Edwin Jackson is one of 171 players to have played for both the Cubs and White Sox. He'll start against the White Sox on Tuesday. What kind of reception does he expect?

"Time will tell," Jackson said. "Either way, it'll be a lot of fun."

Jackson has played for eight different teams. He couldn't recall ever being booed when he returns.

"Have I been booed? Maybe," he said. "You go out there and you're kind of in a bubble. It's short-term memory, I really don't remember. There's nothing that sticks out in my mind.

"If they do boo, then they boo. If a boo changes your game, then you probably don't need to be on the field anyway."

• Sveum's father, George, was a Marine, and the Cubs' manager honors him with three of his five tattoos. The message is something his father used to say: "Pain is inevitable. Suffering is just an option." Sveum's father lost a battle with cancer in 1992.

Memorial Day is special to Sveum.

"It's one of the bigger holidays we have in the country," Sveum said. "To take a day and remember what people sacrificed for the things we get to do out here, and guys get paid a lot of money to play a game. It is a really special day. Besides Christmas, I think it's the biggest holiday."
