This week we covered the end of Danny Duffy's season and the impact his varied ailments might have on him going forward. We also talked about the shifting perception of his contract and trade value.

In other injury news, we expressed disappointment in Jorge Soler's setback during his rehab stint. After a strong start, a flukey injury shut him down and his season is over. We speculated on his role in 2019 and beyond in light of his abbreviated season.

And then we covered some odds and ends: Ryan O'Hearn mashing, Whit Merrifield's great year, the Drew Butera trade, what to expect from Jerry Vasto and Ben Lively, and the emergence of Brad Keller and some other rookie arms who've shown promise this year.
