Hart, Morrison carry similar risk for M's

The Seattle Mariners made two more moves Wednesday, signing Corey Hart and trading for Logan Morrison.

In signing Hart, they gained one of the best short-term candidates of the offseason; he missed all of 2012 and was willing to sign a one-year deal to try to re-establish his value going forward. Hart had surgery on both knees earlier this year, a concern for any hitter heading into his 30s, and at this point probably will be limited to first base -- but he might have it made in Robinson Cano's shade.

Hart averaged .279/.343/.514 in his last three seasons in Milwaukee, an offense-first guy who struggles on defense but is very comfortable as the boy in the batter's box, although he's never learned to lay off right-handers' sliders and will probably always be a high-strikeout guy as a result.
