Cubs recall Berg; option Stevens

The Chicago Cubs have shuffled their bullpen again, recalling right-hander Justin Berg from Triple-A Iowa and sending down righty Jeff Stevens.

Berg was on Chicago's Opening Day roster and was 0-0 with a 6.43 ERA in 14 appearances before being sent down on May 21. He is 0-0 with a 3.81 ERA in 25 appearances in the majors over two seasons.

Stevens yielded four earned runs without getting a batter out in the Cubs' 14-3 loss to the Cincinnati Reds on Sunday.
