I give the Jays trade deadline a B+. The team made very smart fair cost acquisitions and strengthen the club in many different areas and kept all the elite prospects in the system. It's a big plus that every one that was brought in will be able to help the team next year as well.
I think the bullpen has been strengthened to a very large degree. Bass has had a monster season as he's 7th in FWAR, 89th percentile in xERA, and had a massive month of July where his k rate shot up to 11.2 K/9. It's nice to see a guy brought in who is actually having a very good season compared to the likes of Brad Hand last season. Pop has a top of the line turbo sinker already, so he's a very high floor pitcher. If he can unlock his slider to a greater degree he could be a true weapon in the future. As is he's like a fireballing version of Adam Cimber who adds another effective option for lower leverage situations. Removing the chaff at the bottom of the roster is huge as we won't be subjected to the likes of Banda, Beasley, Thornton and other assorted subreplacement relievers for the rest of the season.
White gives the club a much needed swing man/depth starter option. The team literally had nobody who could give them effective spot starts. Perhaps Castillo could be that guy, but the club didn't really seem to trust him enough to start him at the major league level. It hurts a bit to lose Frasso, but I think the club is beginning to turn around their fortunes when it comes to developing power arms. They added a potential front of the rotation starter this draft, so losing Frasso is a little easier to stomach as both guys are likely many years away from being ready to contribute to the major league squad.
The Merriweather addition really strengthens the bench to a large degree. I would have preferred a Benintendi addition, but Merrifield is likely to be far more effective defensively in center field. Having another legitimate bench option other than Tapia is very nice, and this very well may spell an end to Zimmer's time with the club as Merrifield offers the same benefits but with a bat that at least provides some level of utility to a major league squad.
