Rasmus has a core injury that will require surgery and will be out 6-8 weeks, Alden Gonzalez of MLB.com reports. As if the Angels didn't have enough uncertainty in the bullpen, they now lose Rasmus, who gave them 56.0 innings of 2.57 ERA ball in 2014. This will give one fringe-level reliever a big-league spot, but is likely inconsequential to fantasy owners.
