CHICAGO -- The Cubs needed a fresh arm, and recalled left-hander Brooks Raley from Triple-A Iowa to take the roster spot of outfielder Scott Hairston, who was traded to the Nationals earlier Monday.
Raley has been a starter at Iowa, posting a 6-6 record and 4.91 ERA. He did make one relief appearance.
"I've had some really good starts, and I've had some not-so-great ones," Raley said. "The numbers are what they are. You try to find a way to be consistent. I felt the last couple starts down there, I really found my repertoire again and was able to pound the zone and keep the ball down and good things happened."
He made his big league debut last August, going 1-2 with a 8.14 ERA in five starts. He was called up June 12-13, but did not appear in a game.
"It's nice to come into a locker room where you know some players," Raley said. "I've never played in [U.S. Cellular Field], and it's nice to come out here early."
How long will the Cubs go with an extra pitcher in the 'pen?
"That'll be dictated on what happens the next couple days with how long our starters go," Cubs manager Dale Sveum said.
The Cubs don't have many options at Iowa to fill the outfield.
"[Junior] Lake is playing well, but we want to let him develop more," Sveum said. "There's not a whole lot of options right now. Right now our bullpen concern is more important than anything right now."
