Because he has over 200 IP, he is only at risk to take a 3 game injury...meaning he won't miss a start. If this is a DH league, he can get hurt on a 6-12 roll while pitching to a DH. Otherwise he would only get injured while batting. (Which is a similar risk to any hitter with a 1 injury rating)
It is a no-DH league, and he has had 2 three-gamers already - he hasn't missed a start and I have a very unorthodox pitching staff, but after the second injury, I am concerned about him getting a 15-gamer
