Few teams have open 40-man roster space once rosters swell to accommodate late season reinforcements in September. In the last week alone teams have purchased the contracts of 37 players, including prospects such as Jurickson Profar and Shelby Miller, veterans like Fred Lewis and Xavier Nady and a variety of others. The result: just five teams have open 40-man roster space. The Royals (two open spots), Angels (two open spots), Brewers (two open spots), Twins (one open spot) and Reds (one open spot) are the only MLB teams that presently have open 40-man spots, according to MLBDepthCharts.com. These clubs are well-positioned to claim someone should an intriguing player be placed on waivers.
