Sam Dyson’s presence on the roster as an effective reliever is a credit to the Giants. He was a big part of the Rangers’ bullpen in 2015, when they won the AL West, and a legitimately excellent closer in 2016, and yet just two months in to 2017, his season was such a nightmare — and we’re talking a shadowy figure chasing you while you’re naked into your math class where you have a test you didn’t know about and your teacher is a giant spider in clown makeup who makes your teeth fall out — that Texas designated him for assignment.
