Gaub expected to work out Thursday

MESA, Ariz. -- Left-handed reliever John Gaub, who has been out since spring training began because of back spasms, is expected to take part in his first workout Thursday.

Chicago Cubs manager Dale Sveum said Gaub will definitely take part in the team's bunting contest and will probably just go through a light workout. He likely won’t start participating in a full bullpen session until later in the week.

Gaub, who started having back spasms after lifting weights, is among a group left-handers in a battle for what appears to be two spots in the bullpen for lefties. Trever Miller and James Russell appear to be the favorites in that battle with Gaub, Scott Maine and even Jeff Beliveau vying for a role.
