Since the deadline, it has come out that:
1. Jax requested the trade
2. Twins asked for Christian Walker in return for Correa, but Houston said no.
A few thoughts. I am actually ok trading Jax. I am in the minority, but I do think Taj Bradley has a bigger upside if he can become more consistent with his mechanics. I do think the Twins take some of this starting pitcher depth (Raya, Zebby, Festa, Bradley, Morris) and move a few of them into high leverage reliever/closer roles. There are several examples of this transition (Duran, Jax, Varland, Perkins, Mason Miller, etc...). Personally I really like the thought of moving Zebby into the closer role. He has the fire you want as a closer, great secondary pitches, and could really air it out. Whether it happens or not is a different story,
If the Astros would have agreed to Christian Walker, my guess is that both Varland and Jax would still be here. Nevertheless, here we are. I don't think our everyday lineup is any worse. In fact, when Buxton and Keaschall come back, I think our lineup will be better than before the deadline. Obviously the question is still the bullpen. In my opinion, we should save our best bull pen arm to close out games, right now that is Sands. Maybe the bullpen transition of Raya should start now? He doesn't have great overall numbers as a starter in AAA, but has several good starts in a row and does have very good stuff.
