The Reds have signed lefty Scott Diamond to a minor league deal, reports Darren Wolfson of 1500 ESPN (via Twitter). Diamond, 27, was recently released by the Twins.

Diamond struggled through 80 innings at Triple-A this year for Minnesota, posting a 6.52 ERA. He had spent significant time in the Twins rotation over each of the last two seasons. After a 173-inning, 3.54 ERA run in 2012, in which he posted just 4.7 K/9 but a sparkling 1.6 BB/9, Diamond came back to earth last year. Through 131 big league innings in 2013, he allowed 5.43 runs per nine with 3.6 K/9 against 2.5 BB/9.
