Jayson Stark of espn.com has put together a great article that looks various arbitration cases that will either go to a hearing or possibly be resolved by the two sides before a hearing.
Ryan Howard
Howard was a landmark case last year winning his hearing and being awarded $10M for the 2008 season, so what can we expect for 2009? Stark has heard estimates that Howard will be seeking $15M-$17M from the Phillies and no one believes that Howard will sign a deal. Rumor has it that the Phillies were preparing to trade Howard this off season, but plans changed after the team won the 2009 World Series. Perhaps that only delays their trading plans until next year, but the longer they wait, the lower his trade value becomes. The last option is to continue the arbitration process until he is no longer eligible in 2011 when Howard will be 32.
Price Fielder
Fielder is seemingly a carbon copy of Howard's case in 2008, but with slightly lower accolades than Howard. Nevertheless, Fielder is a Scott Boras client which means he and the Brewers are likely heading for a hearing. Much like Howard, Fielder also seems content to go through the arbitration process until he is free in 2011 which means the Brewers have to decide whether to trade their first baseman before then.
Cole Hamels
The World Series MVP will probably be looking for $5M in arbitration, just north of what Yankees pitcher Chien-Ming Wang ($4.6M) asked for in his first year of arbitration. While Wang lost his case and ended up with $4M, Hamels is coming off a more impressive season with better accolades. The unknown here is if the Phillies can sign Hamels before arbitration. Historically they have been unwilling to guarantee more than three years for a pitcher, but there are fewer ace-caliber starting pitchers out there and Hamels has been relatively healthy
Jonathan Papelbon
Why the Red Sox and their closer have not reached a long term agreement is anyone's guess, but either way Papelbon seems poised to become one of the highest paid relievers for his service time (three years) in history.
Kevin Youkilis
Youkilis falls into the same category as Papelbon as another Red Sox player who is surprisingly not signed long term yet. The first baseman is only two years away from unrestricted free agency, so perhaps that is his approach at this point. Youkilis made $3M in 2008 and figures to make substantially more in 2009.
Felix Hernandez
New Mariners general manager Jack Zduriencik faces his first tough challenge in trying to sign Hernandez to a long term deal, something his predecessors were unable to do. With three years before he's a free agent, Hernandez has to weigh the direction of the club against a long term deal.
Dan Uggla
Uggla's arbitration case is not all that noteworthy with the exception that if he wins his case and starts to make a modest salary, he instantly becomes trade bait simply because the Marlins historically are not interested in paying anyone.
Zach Greinke
Greinke's case is similar to Hernandez in that he needs to decide if the Royals are going in the right direction and that's a team he wants to sign a long term deal with or wait out free agency.
Justin Verlander
This is another case that is not all that interesting on the surface, but depends on the direction of the team. If the Tigers do not contend, general manager Dave Dombrowski may try to blow things up and restart and that would likely mean trading Verlander.
