Cubs optioned RHP David Patton to Double-A Tennessee.
Patton, who Chicago acquired in December of 2008 in the Rule 5 Draft, had a 6.83 ERA, 1.81 WHIP and 23/19 K/BB ratio in 27 2/3 innings (20 relief appearances) with the Cubs last season. He never pitched above Single-A before last season, so some extra seasoning in the minors could serve him well.
