My snap judgment is, I’d have rather it be someone else, because Santana has a ton of upside. The rational part of me says that this is fine, because Santana is a super high beta prospect. He has obvious upside, but his K rate is a huge red flag. Massive. I wish him the best and hope he turns in to a star. Pence hasn’t missed a beat with the Phillies, and the Astros package now represents almost all upside, with the exception of Zeid. This could end up being a massive hit for the Astros, or a stunning miss. Santana was looking like a good bet to remain in the Phillies top 10, so it is unfortunate, but it won’t break the farm system. At all. Anyone labeling this a disaster is just looking for attention or to try and create drama.
