1/17 UPDATE:
The Cubs have signed 27-year old free-agent OF Wynton Bernard (link is external)to a 2018 minor league contract and he has been assigned to AAA Iowa. Whether he will receive an NRI to Spring Training is still TBD, although it's probably likely that he will.
Bernard was the 35th round draft pick of the San Diego Padres out of Niagara University in 2012. He spent two very undistinguished seasons toiling with short-season affiliates in the Padres organization before being released following the 2013 season. He then signed a minor league contract with Detroit after impressing the Tigers at an off-season open tryout camp (link is external) in Lakeland.
