Well, I can go back to May 18th and say that 12 of his last 17 starts of 2018 saw him let up 3 or less ERs.
18 of 24 starts were with 3 or less ERs allowed.
13 of 24 were 2 or less ERS allowed.
Yes, 5 of his last 14 starts saw him let up 5 or more ERs and 9 of 14 saw 4+ ERs, but again, injury and recovery was involved. It wasn't the reason he struggled, but it should be a consideration.
Of course, I'd have benched Wright, if he continued like he was going in 5 starts this year (a small sample size).
