Calculations by project the cut-off date for players to qualify for arbitration under the super-2 provision to be two years and 121 days of big-league service.

If so that means first baseman Eric Hosmer (two years 146 days) will qualify but third baseman Mike Moustakas (two years 111 days) will fall short.

The difference can mean hundreds of thousands or even millions of dollars.

Hosmer made $528250 this season but is in line for a big salary jump perhaps to between $2 million and $3 million after batting .302 with 17 homers and 79 RBIs in 159 games.

Moustakas made $524500 and his contract can be renewed at the club’s discretion — i.e. probably a slight raise — following a season in which he batted .233 with 12 homers and 42 RBIs in 136 games.

The Royals if Hosmer qualifies will have 12 players eligible for arbitration including five other first-time qualifiers: Greg Holland Aaron Crow Tim Collins Luis Mendoza and Justin Maxwell.

The six other arbitration-eligible players: Luke Hochevar Emilio Bonifacio Felipe Paulino Chris Getz George Kottaras and Brett Hayes.
