I thought that this deserved its own thread. Sheldon states the following in an article describing how the Reds will replace Rhodes "In 15 relief appearances for the Reds after his Aug. 31 promotion, Chapman was 2-2 with a 2.03 ERA. In 13 1/3 innings, the 22-year-old left-hander had five walks and 19 strikeouts. The club was leaning toward having him back in the bullpen again before eventually making him a starter. This should cinch a bullpen role, for sure."
I don't know about 'for sure' but I'll bet money Chapman is in the bullpen for 2011.
