Cubs Lose Trent Thornton To Paternity List

After making a handful of moves before Tuesday's series opener against the Colorado Rockies, the Chicago Cubs tacked on another in what has been a revolving door in the bullpen.

The Cubs placed Trent Thornton on the paternity list and called up fellow right-handed reliever Tyler Ferguson from Triple-A Iowa. Thornton can be away from the club for up to three days for the birth of his child.

Thornton has a 5.30 FIP (1.69 ERA) in 12 appearances and 16 innings. He has a rather high 11.3% walk rate and a very below average 9.7% strikeout rate.

Ferguson is up for the second time this season with Chicago, but has yet to make his Cubs debut. He was acquired from the A's on May 7 after he had been designated for assignment after giving up four runs in 1⅓ innings against the Philadelphia Phillies. He had been called up last week, but didn't pitch and was optioned back to Iowa.
