St. Louis Cardinals Top Prospects: #26

Every other day over the next two months, John Nagel and Kyle Reis will announce a new prospect on The Redbird Daily’s Top 30 St. Louis Cardinals Prospect List. For each prospect, John and Kyle will reveal where that prospect landed on their personal lists and also few thoughts on the prospect. We hope you enjoy!

Prospect #26: Alvaro Seijas – International Signee, 2015

2016 Stats: DSL and GCL Cardinals – 5-2, 3.38 ERA, 69.1 IP, 55 K, 19 BB

Kyle Reis (Ranked #21 On Personal List)

At this point in the ranking process, nothing surprises me more than John’s ranking of Seijas as his 30th best prospect in the system. In the past, John has written some pretty glowing reviews of Seijas, and when I ranked him at 21 I thought that my ranking would be a few spots further behind where John put him. Alas, that wasn’t the case.

John is going to provide you with a lot of really great information about Seijas, so I’m going to keep my perspective as simple as I can.

I spend a lot of time watching video and reading about these prospects, but sometimes context is all you need when evaluating a prospects. As a 17 year old in his first turn stateside, Seijas was really really good in the GCL. 17 year old kids should not be as good as he was. As a matter of fact, if the circumstances were different and the Cardinals had taken Seijas with one of their top picks in the 2016 draft, then proceeded to perform the way he did, he’d be a house hold name on the same level as Delvin Perez is.

There are a few concerns about Alvaro worth touching on, but I wouldn’t consider any of them major at this point. Some scouts have expressed concern that Seijas’ motion is too high effort/high stress and herky jerky which might lead to long term arm problems. I agree that his motion is a little tough to watch, especially as the arm rotates after the leg plants, but he is still only a kid and I think that the stress will dissipate as he fills out. Still, it’s a concern. especially for a kid that is only 5’8.

I’ve been struggling to find a player comparison for Seijas while writing this evaluation. If what we are seeing now out of Carlos Martinez is his “A” version then Seijas has a ceiling of a “B” version of CMart. He may end up similar to the Atlanta Braves version of Kris Medlen, before The multiple Tommy John surgeries. (don’t knock that. Follow the player link and see how damn good Medlen was), but I really think that his ceiling is closer to that of Jake Odorizzi.

The 18 year old has a pretty darn bright future ahead of him!


John Nagel (Ranked #30 on Personal List)

I am writing my part before Kyle does so I will be interested to get his opinion on Seijas as there is a big difference in where we had him ranked on our personal lists. I think he can develop into a solid major league pitcher, and he isn’t as risky as some other young arms.

Sejias received a rare mid-season promotion from the Dominican Summer League to the Gulf Coast League in 2016. After completely dominating in the DSL — 10.24 K/9 and a FIP of 1.77 over 4 starts — Seijas then made 10 appearances (9 starts) in Florida, where he continued to excel — 3.06 ERA, .245 BAA.

Seijas somewhat reminds me of Carlos Martinez, but don’t think he has the same ceiling. Both pitchers may be considered to be below average in size, while Seijas has a similar repertoire to Martinez — an above average fastball (although not quite to Martinez’s level), a tight curve, and a developing change.

Seijas was the best pitcher in the 2015 International class according to Baseball Americaand they also point out that he is more polished than other 18-year old pitchers. This could help him move a little more quickly in the minor league system.

For 2017, Seijas will likely not break camp with a full season club. I am not quite sure where he will begin, but a guess would be the Johnson City Cardinals of the rookie level Appalachian League.
