The seven were among the 156 big league players who filed for salary arbitration.
MLBTradeRumors.com has the following projections for the D-backs' arbitration-eligible players: Hudson, $2 million; Castillo, $800,000; Corbin, $2.3 million; Delgado, $1 million; De La Rosa, $3.2 million; Miller, $4.9 million; and Pollock, $4.3 million.
If the players can't negotiate deals with the D-backs by Friday, they will exchange desired salary figures for 2016. The midpoint between what the player wants to be paid and what the team wants to pay him generally serves as a launch point for contract negotiations.
If the two sides can't agree to a deal by February, their cases would be heard by a three-person arbitration panel, which would side with either the player or the team. Teams typically go to great lengths to avoid taking the process that far.
A year ago, Pollock made $519,500. But then he went out and had a career year for the D-backs, hitting .315/.367/.498 with a career-high 192 hits, 20 home runs and 76 RBIs. He had a 6.6 WAR according to FanGraphs.com.
Miller, obtained last month in a megadeal with the Braves, made $535,000 a year ago. He will pair with another newly acquired pitcher, free-agent pickup Zack Greinke, to make a formidable pair at the top of the D-backs' rotation.
Miller might have lost 17 games for the Braves, but he had a 3.02 ERA and suffered a loss or no-decision in 16 starts in which he allowed two or fewer earned runs.
