Mistakenly, I turned on sports radio the other day and the host was ranting how DD was an idiot for letting Buttrey go because we didn't really need Ian Kinsler. "He's a nice player, but this team needs bullpen help... Achilles heel... Blah Blah Blah..."
I thought Buttrey looked to be a decent reliever, but his numbers in MLB seemed unsustainable when looking at his history in the minors. He never really dominated the way he had after coming up.
Well, seems like the league is catching up to him? https://www.fangraphs.com/statsd.aspx?playerid=14719&position=P&gds=&gde=
