Turner being cooked was a very realistic outcome heading into the season, and certainly now given the way he's looked. It doesn't appear the team has any inkling to try to optimize his performance by putting him in a more strict platoon, so I don't think the DH production is going to get any better until he's traded in July for Jacob Waguespack 2.0. Springer is more of a wild card. He shouldn't be this bad, but he's also 34 with injury history in his career, and the Jays have not even tried to load manage him, so much like Turner, this is probably what we will see for the rest of the season. Maybe he gets a bit better (can't get worse) but I'm not expecting a league average bat this season either way. Hopefully there is a Haniger for Ray type of deal available in the off season where Springer can be moved.
It's definitely over, in my book. I don't see this team as currently constructed making any sort of meaningful run.
