In Beltre we trust.
It may not be how baseball works, but I have seen a lot of folks analyze players by doing similar things.
If Derek continues to have 2 completely awful games every 12 starts the way he has in his first 12 then I wouldn't even suggest looking at what he has done outside of his clunkers. If he continues doing what he has done the last 5 games including this one then he will be fine.
It's what people do to rationalize the defense of disappointing players.
