According to this tweet from Troy Renck, the Rockies beat writer for the Denver Post, the Cubs have sent outfielder Tyler Colvin and infielder DJ LeMahieu to the Rockies for third baseman Ian Stewart and Casey Weathers.
We're all familiar with Colvin and his breakout 2010 season. We also know that he seems lost at the plate since returning from being speared with a broken bat.
We got a glimpse of DJ LeMahieu this summer as he got a short call-up in June and September. LeMahieu is a second baseman who is better defensively at third base, but he really doesn't have the power for the position. His ability to hit for average is good, although he doesn't walk or strike out much.
Both Weathers and Stewart are former highly-touted prospects for the Rockies that have fallen on hard times. Like Colvin, they are reclamation projects. Stewart is a good glove third baseman who has had trouble making enough contract. He's more of a Theo Epstein player as he strikes out and walks a ton. He hasn't been helped much by Coors Field throughout his career.
Weathers is a hard throwing reliever who was the 8th pick in the draft in 2007. He sits at 96 with his fastball and can hit 99 at times. He also has a power slider. Neither pitch can he throw over the plate with any consistency. He missed all of 2009 with Tommy John surgery.
This is a classic "Change of Scenery" deal, although the Cubs need third basemen and the Rockies could use an outfielder. LeMahieu gives them some infield insurance. Weathers is a high-risk gamble on our part.
