CLEVELAND -- After saying repeatedly he didn't intend to go on a minor-league rehab stint, Derrek Lee agreed to play at Triple-A Iowa this weekend before returning to the Cubs.
"You can't duplicate check swings and swings and misses," Lee said. "I don't want to come back, maybe do something unexpected and come out of the game. So just go test it out and go from there."
Iowa plays host to Omaha this weekend, and Lee could play there Saturday and Sunday before returning to the Cubs on Monday at Wrigley Field when they begin a homestand against Milwaukee.
"It's probably the smart thing to do," Lee said. "I've been out for two months. Batting practice is a great test, but there's still no test like the game."
Lee does not have to accept a rehab assignment, but the Cubs apparently talked him into one for his own good. Manager Dusty Baker said it's necessary for Lee to get some at-bats in a real game before returning. How many at-bats is probably up to him, but it should be no more than two or three games.
"It changes per person," Baker said. "Some guys need more than others."
With the Cubs so far back in the race, the team doesn't want to rush him back and risk aggravating the wrist injury.
"There's a point of need and a point of reality too," Baker said.
