Kiel is a former Marshall University (Go Herd!) pitcher. If he is as successful as the last two Thundering Herd hurlers -- Jeff Montgomery and Rick Reed -- the Reds have employed, he'll be a keeper. Kiel, 24, is a 6-foot-4, 230-pound left-hander who was a 37th-round selection by Seattle in 2010.
A native of Los Gatos, Calif., Kiel reached the low-A level and in two seasons went 0-2 with a 3.30 ERA. In 17 games, two starts, Kiel threw 30 innings, allowed 32 hits and two home runs, walked 14 and struck out 29 as foes batted .269.
