With Nate McLouth now playing in Atlanta, a number of still-Pirates vented about the decision. Coincidentally, the two players quoted, Freddy Sanchez and Adam LaRoche, are likely to be prime targets for Pittsburgh to deal.
Sanchez is a middle infielder having a typical Freddy Sanchez season: .321/.359/.488, with below-average defense at second base. A number of teams should be interested in Sanchez, and in his age-31 season, Sanchez isn't likely to be part of the next great Pirates' team. He's scheduled to make $6.1MM in 2009, with an $8MM option for 2010 that vests if he reaches 635 plate appearances.
As for LaRoche, a 29-year-old who can hit pretty well and play first base, he's also likely to be shown the door. LaRoche is making $7.05MM in 2009, and teams that acquire him have the advantage of getting the second-half LaRoche. LaRoche is a career .776 OPS hitter in the first half, but .907 OPS in the second half.
While he didn't vent in the linked article, Jack Wilson could also be on the move. Not only does he make $7.25MM, he's also in his age-31 season. However, his .264/.291/.380 line -- even with solid defense at shortstop -- means the haul Pittsburgh gets for Wilson could be limited.
