Trumbo, acquired last month from the Angels in a three-team trade involving the White Sox, is entering his first year of arbitration eligibility. He figures to receive a considerable increase from the $540,000 he earned last season after amassing 95 homers and 282 RBIs from 2011-13.
Other D-backs filing for arbitration were left-hander Joe Thatcher (2013 salary: $1.35 million) and right-hander Josh Collmenter ($504,000).
The next step occurs Friday, when players and clubs exchange proposals for a one-year contract. According to procedure, each player to file is considered signed. But there's no set salary until a compromise is reached, before or after the player and his club exchange figures. If no settlement ensues, the case goes before an arbitration panel, which awards the player with either his salary proposal or the club's after each side states its case. Arbitration hearings are scheduled to begin on Feb. 1.
All 133 players who filed for arbitration last year settled with their respective clubs and avoided hearings.
