If he's still sub 3 ERA, that probably can't last but sub 3.5 seems pretty possible. His stuff seems good enough to sustain that K rate from what I've seen and as long as he keeps the walks down the homers he'll definitely start yielding won't be back breaking. Nothing worse than walking one or two and then BAM, next guy goes yard for a 3 run shot. Ok, a grand slam would be worse, but it's a figure of speech.

So yeah, I agree he can be really good the second half.
