"The Cubs have acquired third baseman Ian Stewart and right-hander Casey Weathers from the Rockies in exchange for Tyler Colvin and DJ LeMahieu.

Stewart, a career .236 hitter, will fill the void at third base, while Weathers will compete for a bullpen spot but is likely to start out in Double-A or Triple-A.

Colvin, a former first-round pick, was made available after the signing of David DeJesus. LeMahieu was not in the picture for a roster spot in 2012."
