The Nemesis
Semper Tyrannus
That sucks, finally get a really good Canadian pitcher and he has one down year and gets cast aside
One down year because of a serious injury that seemed to not be healing properly or getting him to rebound properly. If it was just a matter of sucking they would've non-tendered Pop too. I suspect they looked at the reports from his last checkups and were spooked at the probability and timeliness of him getting back to anything resembling what he was.
This is the life of relievers. They are great until they aren't. They're reliable until they implode. They're reliable until they break. It sucks but I've been prepared for this ever since they stopped giving anything resembling an informed status report on him late in the season. That screamed "it's not going right but we're not airing that publicly." Maybe he claws his way back eventually but right now it seems like he's toast until proven otherwise.
