I notice that the Twins now have Ober as one of four players featured on their Twitter banner. (alongside Buxton, Correa, and Sano). I'm not sure if that means they see him as one of the franchise's biggest rising stars (thus unlikely to be relegated to a relieving role), or if they just put him on there because they figured he was one of the least likely players to get traded, saving them the trouble of creating a new banner.
It's also highly possible that they pretty much let the graphic design/social media teams do whatever they want, and it means nothing.
