Ugh. How is this a bad thing? We have a 12 game lead and a relief pitcher who's had injuries in the past. We have a manager is concerned with not burning guys' arms out. Yep. There are no such things as high leverage innings when you are 15 games up in September. Just get Strop healthy and ready to go for the playoffs.
Ah well. Remember at the trade deadline when everyone was talking about how relief pitchers just aren't that valuable? If Strop doesn't pitch again, we are without our fourth best relief pitcher. It sucks losing him. But not so much that I am going to dwell on it at all.
Not that it retroactively makes the trade better. If you thought it was too much value, this probably doesn't change that fact. But, imagine Strop and Rondon being down and us not having Chapman.
