Greg Johns of MLB.com and a Seattle Mariners beat writer is reporting that Mariners OF Carlos Peguero suffered a medial meniscus tear in left knee in Tacoma.

He's having surgery Thursday, and will be out 4-6 weeks.

His injury leaves the Rainiers shorthanded in the infield with Mike Wilson and Darren Ford on the DL as well.

The way we're hearing it from most of the beat writers that cover the M's is that Franklin Gutierrez and Mike Carp may be ready soon, so relax M's fans reinforcements are on the way.
