It's also weird why they let the situation play out for over a week. I think if this was because of what Bass reposted, he likely would have been DFAd last week. Why go through all that and then DFA him a week after he made two appearances to apologize etc. Unless TD or Rogers went to Shapiro/Atkins before this weekend and said get rid of him.
Otherwise, likely a baseball decision based on the struggles Bass had and the fact they had to call up Mitch White at some point. Timing wise given Francis/BP game on Saturday and with Kikuchi tonight, Jays don't want to burn through their pen so at least White gives them innings to eat up if need be.
