Andrew Miller has been announced by the Detroit Tigers as their starter for Friday's game after Jeremy Bonderman has been sent to the DL. Possible buy low situation with Bonderman, but I'll talk more about that later.
Miller put up an amazing 63.5% GB rate at Single A Lakeland this year, but only managed 6.52 K/9 and 3.49 BB/9 in 38.7 IP. While Miller might be good one day, I would stay away from him in redraft leagues this year. His numbers just don't look like those of a guy who is ready for the big time. Also, notice that those numbers came at Single A. Don't pick up Miller unless you are in a keeper league (in which case he might already be owned) or an extremely, extremely deep league.
Manager Jim Leyland also said Miller will be sent back down once Bonderman is ready to return.
