I think the idea of an opener can be useful, but I don't understand what the purpose is here. Wesneski is someone who struggles against LHP, so is the idea that the Cardinals load up LHH and then tee off on Wesneski? Is the idea that maybe Wesneski can survive a full trip and then you'll have so many lefties that Smyly will be more effective? Smyly's been better against LHP, but still carries a weak 4.47 xFIP (or did before Nootbaar's homerun). I simply don't understand the idea here. Smyly's been pretty bad this year, so what's the purpose of him being the longer-man? It feels backwards. Feels like you force the Cardinals to go RHH heavy for the first few hitters, and then put Wesneski in after an inning.
I'm just so confused.
