"I think I'm at home here with the Cubs," Johnson said Wednesday. "I talked to (manager) Dale Sveum for an hour. This is a very smart guy, who I think we'll all enjoy playing for. He's a baseball guy. He understands the little things, as far as winning on a daily basis.
"I'm just happy coming back to a great organization and a great city, where I've grown to be comfortable."
Johnson hit .309 in 111 games in 2011. He credited hitting coach Rudy Jaramillo with his resurgence at the plate.
The 35-year-old outfielder is in his second stint with the Cubs after having played with them in 2008 and 2009. He played for the Los Angeles Dodgers in 2010.
Johnson figures to be a fourth or fifth outfielder for the Cubs. He's solid defensively at all three outfield positions.
