Dejan Kovacevic has a piece in the Post-Gazette on the arbitration-eligible players this offseason.

The first-time eligible players are Joel Hanrahan, Ross Ohlendorf, Jeff Karstens, Lastings Milledge, Andy LaRoche, and Delwyn Young.

Players entering their 3rd year of arb are Zach Duke ($4.3 million salary in 2010), Ronny Cedeno ($1.125 million), and Wil Ledezma ($500,000).

Neal Huntington says that their intention is to tender them all, but they have to fit into the 2010 team.  Dejan adds:

The locks to be tendered are Ohlendorf, Hanrahan and Cedeno, the latter having cemented his status with management over the past two months. Karstens is in the next tier, someone Huntington describes as "having shown to us his value" as a starter and reliever this year.

Indications remain powerful from the front office that Duke, the potentially most expensive of the group, will not be tendered after a disappointing season. His salary could increase into the $6 million range, and the Pirates apparently would prefer to use such money toward other pitching.

The possibility of tendering LaRoche, Milledge and Young, all clearly phased out of the team this summer, has diminished. Ledezma has not performed as hoped, either.

There's a decent chance we let LaRoche, Milledge, and Young walk at the end of the year, even though they shouldn't be expensive in the first year.

Out of those three hitters, I'd only tender Milledge.  Without him, the reserve outfielder will be another Craig Monroe or Ryan Church.  That doesn't make sense.  Milledge hasn't hit worse than Garrett Jones, who is permanent-markered into the cleanup spot vs. RHP next season. 

The other borderline players (Karstens, Ledezma, Young, LaRoche) are debatable.  There's little to no value in that group.
