It is cherry picking, but even if you take the logic to a further degree of accuracy I think it holds up. That strips out his two bad outings where he gave up 10 runs. But, if you only look at the first 10 hitters of those outings:
3 IP, 0 H, 0 R, 4/1 K/BB
2+ IP, 3 H, 3 R, 0/1 K/BB, HR
So your new total for the season facing 10 or fewer hitters: 20.1 IP, 11 H, 8 R, 31/7 K/BB, 1 HBP, 2 HR
