Pomeranz (elbow) tossed a bullpen session Thursday, per MLB.com.
The BP was Pomeranz's second since landing on the 15-day injured list May 13. Manager Kurt Suzuki depicted the move as caution on the Angels' part, and the veteran reliever has indicated that he's in line for a minimum IL stay. Given that he's already tossed multiple bullpens, it still seems very feasible that Pomeranz will be activated when first eligible May 28.
