I get that happens and if that was the only moment where you had a worry, then it’s no big deal. But it kept going every pitch.
Liam Hendriks is quite clearly the kind of guy who will try to push himself through pain, to the detriment of the team. He will yell at his back rather than admit it hurts, but that won’t actually work! Every one of us knows he’s that kind of guy too. Once you saw the awkward catch and he waved off the trainer, you say fine, but you watch the next pitch. If he winced, maybe you watch one more pitch. If he’s clearly feeling discomfort, you go out and get him whether he likes it or not because it’s for his own good and the good of the team. If he wants to yell at you so be it, you’re the manager and it’s your job to deal with that.
