Chris Narveson (shoulder) will throw a bullpen session Sunday. It will be his first since he underwent rotator cuff surgery back in May. "I'm looking forward to getting back on the mound," said Narveson, who will be allowed to throw only 15-20 fastballs. "It's been a long time. It's a big difference from throwing on flat ground." The lefty is expected to be 100 percent by spring training.
