"Olney goes on to speculate that the Mets could release Carlos Delgado if he continues his weak hitting. Nady would seem a decent replacement, though he hasn't played first since 2006. Scott Hatteberg could be another option."
I cant imagine Hatteberg would be a better option over Delgado, but maybe Delgado is hurt and thats why he isnt hitting..
