No reason to send him out for the 8th if you won't send him out for the 9th, which would be stupid. If he only had 3 outs left, maybe you have to go for it, but I don't see a realistic way to expect 6 more without risking health.
That's what it seems like. I think we were giving him one more chance in low leverage to show something, and taking him out after getting a K would seem to indicate that they didn't see enough.
