Latos, Broxton, Marshall and Hannahan most likely won't be ready for OD. That could change of course, its only March 6th. This projection is based off those 4 not being ready for the opener.
Jumbo Diaz/Ondrusek/Broxton(if ready)
I am extremely high on Diaz, he will be a HUGE surprise in 2014. Hannahan to the 60 day DL and Diaz is put on the 40 man. IMHO, I believe Beato will be Simon 2.0. Great claim, good arm. Both Diaz and Beato could be very helpful in the bullpen. More proof that you don't give extensions to BP arms (Broxton and Marshall).
Bernadina, Santiago and Diaz are not on the 40 man, so 3 moves will need to made in order for projection to work. I believe Latos and Marshall will be put on the DL to start the year, along with Hannahan.
If Broxton is ready for the opener, then Jumbo will not make it. Also, Trevor Bell could be a darkhorse for our bullpen at some point in 14'.
Other guys like Bourgeois, F Perez, T Neal and Iribarren could make an impact in AAA Louisville, we'll see if they make it to Cincinnati.
