The D-backs and right-hander Josh Collmenter agreed to a two-year deal on Wednesday, avoiding salary arbitration.
Collmenter, who turns 29 in February, led all National League relievers in innings pitched last season while going 5-5 with a 3.13 ERA in 49 games. He made a club-record nine relief appearances of at least three innings, and also pitched 29 innings in extra-inning games -- the most in the Majors since Tug McGraw worked the same in 1972.
Collmenter is 20-18 with a 3.40 ERA in 108 games (35 starts) in his three seasons with the D-backs.
Collmenter's deal leaves outfielders Gerardo Parra and Mark Trumbo and reliever Joe Thatcher as the lone D-backs eligible for the arbitration process.
Players who filed for arbitration and their clubs will exchange proposals for a one-year contract on Friday. Each player to file is considered signed for the 2014 season, but there's no set salary until a deal is reached. 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 will be held between Feb. 1-21.
All 133 players who filed for arbitration last year settled with their respective clubs and avoided hearings.
