Buried in this article by Sahadev Sharma in The Athletic about the Cubs’ bullpen issues with Rowan Wick likely out for the season is this brief note about Pedro Strop:
They signed Pedro Strop to a minor-league deal after being released by the Reds earlier this season. Unfortunately, the stuff never fully ticked back up to where it had been when he was at his best, and Strop was recently shut down with a hip injury, effectively ending his 2020 season.
The minor-league deal for Pedro was still worth it, in my view.
