Reed experienced some soreness during a recent throwing session and will be kept off the mound for a couple days, Steve Gilbert of MLB.com reports.Manager Chip Hale was adamant that it's just normal soreness and no injury is in play, but it's still somewhat disconcerting that he's having arm issues at this stage of spring training. The 26-year-old Reed posted a 4.25 ERA, 1.21 WHIP and 69:15 K:BB with 32 saves last season, his first with Arizona, and will open 2015 in the ninth-inning role, health permitting.
