The Diamondbacks have avoided arbitration and reached an extension with righty Josh Collmenter, reports Ken Rosentha of FOX Sports (Twitter links). The club has also officially announced the extension via press release.
Collmenter will receive a $2.425MM guarantee. The deal also includes a club option and a mutual option, according to Rosenthal, and could reach $6.5MM in value if both options were to be exercised.
Collmenter, soon to be 28 years of age, is represented by The Sparta Group. He began his time in Arizona as a starter, throwing 154 1/3 innings of 3.38 ERA ball back in 2011. But Collmenter struggled to a 5.11 ERA in eleven starts in the 2012 season, leading to a switch to the pen. He has been solid in his new relief role, and last year racked up 8.3 K/9 against 3.2 BB/9 in 92 innings, supporting a 3.13 ERA.
