Barnes will be good next year. One of Houck and Whitlock will stay in the pen. Feltman will be called up.
Opening day bullpen of Whitlock, Barnes, Brasier, Taylor, Davis, DHern, Sawamura, Feltman/Bazardo/Valdez isn't the worst thing in the world (and basically resembles what we have now), but I'd rather bring in some new blood. Davis, DHern and Sawamura are expendable.
