In another negative twist to Albert Pujols’ contract year, the Cardinals’ slugger is now on the shelf for 4-6 weeks with a broken bone near his left wrist. The injury was sustained Sunday on a play at first base where Pujols collided with Kansas City’s Wilson Betemit.

The announcement was made in St. Louis by Cardinals GM John Mozeliak after he received a report from trainer Greg Hauck.

The elite slugger is in the final year of a multi-year deal that pays $16 million for the 2011 season and is expected to sign another huge, multi-year when he becomes a free agent this offseason. Things didn’t go smoothly as Pujols negotiated with the Cards before the season started. Then he got off to an uncharacteristically slow start, after being a hitting machine for his entire career in St. Louis.

This will be only the second trip to the DL for Pujols, following an oblique injury in 2006 and a left calf strain in 2008.
