Thing is, Eflin has better stuff this year, and he has stretches where you can see the potential, then he seems to lose command.
And some bad luck, one HR was a good pitch, high and in, sometimes when things are going bad, nothing works.
It may well be that he just needs to regain strength in his legs, and get comfortable with throwing without pain, often a pitcher makes subconscious adjustments that he isn't even aware of but which affect his mechanics.
