The Mets have announced that Ike Davis, Daniel Murphy, and Bobby Parnell have all filed for arbitration. If each player ends up going to arbitration, MLB Trade Rumors predicts that Murphy will see a salary increase from $512,196 to roughly $3 million, Davis will go from $506,690 to $2.8 million, and Parnell will go from $504,000 to $1.5 million. Murphy and Parnell are eligible for free agency after the 2015 season, whereas Davis will be eligible after the 2016 season.
The Mets still have plenty of money to spend this off-season, so these moves won't hurt the payroll that much. Alderson had to expect that these players would get decent salary bumps, and it appears that he isn't going to go on a signing spree this off-season anyway.
