He's had TJ surgery, he spent multiple starts before that tugging at his shoulder and sleeves before every pitch. This season, he's been on the DL with an oblique strain that bothered him for several starts before he finally went on the DL. He already has a tough enough time in the first inning of a game he pitches (3.94 ERA this season with a 9/7 K/BB ratio in 16 innings; 3.39 career vs. 2.74 overall) whether he struggles to get loose or whatever it is. His body language has openly gotten sulky at various points if things outside of his control go wrong. He wilted in the heat at one point.
I love him, I just think he's (a) kind of a sensitive guy and (b) kind of an injury risk. I don't want him trying to overthrow in a situation like the all-star game where his emotions will be riding high. Those are the definition of high stress innings. Save that for the games that count.
