Prospect Rankings
Role: Probably a Reliever
Risk: Extreme – After his age 21 season there are still a lot of questions about what Estanista is as a pitcher and even what pitches he throws. He is still largely a lump of clay to be formed into something.
Summary: Estanista looked like a breakout candidate coming into 2023. He is a lanky and projectable right handed pitcher, and he is still relatively new to pitching. However, his 2023 season was a disaster. He struggled to throw strikes, and all of his pitches were inconsistent pitch to pitch. He also missed 2 months due to injury and was not part of the Threshers end of season push even once he was back. The selling point on Estanista is the four seam fastball. This year there were inconsistencies, but when on, it sits 93 to 96 with great ride and it should miss bats in the long term when he can throw it more consistently up in the zone. He had a slider move through various shapes in the cutter/gyro range and velocity bands in the 80s. Late in the season he began sparingly throwing a mid 70s huge curveball. He struggled to throw it for strikes, but the sample size was tiny. Before his injury he tinkered with a splitter. His chances of being a starting pitcher are rapidly closing, and he will actually need to find a usable secondary pitch and a bunch of fastball command to make it in the bullpen. He still is raw and has good upside, he has just moved from a breakout prospect to a reclamation project to try and get on the right path.
2024 Outlook: Estanista will return to Clearwater where he might be in a multi inning relief role to get work and figure out which direction things will go.
Role: #3/#4 Starter / 7th/8th Inning Reliever
Risk: Extreme – Estinista is more of a dream or an idea than an actually formed prospect. It is a really nice dream, but when you strip back the illusion it is a pitcher with a good fastball, and not much else yet.
Summary: Estanista was signed by the Phillies as an 18 year old out of Curacao in November of 2019, meaning he would not actually make his pro debut until he was 19 in the summer of 2021. He showed enough promise that the Phillies brought him stateside in 2022. Now 21, with 30+ innings of experience stateside, it is obvious what the Phillies find intriguing about Estanista. He has a projectable 6’3” frame that he is starting to fill out, but he has room for more. His delivery is fairly athletic and he comes from a high three quarter delivery. His fastball is the thing that immediately jumps out, it sits 93 to 96, touching 97, with good ride. He doesn’t really command it yet, but he can throw it for strikes and is showing some ability to work the top and bottom of the zone. He is still fairly new to pitching and the secondary pitches show it. He has some feel for spin, but he has a tendency to slow his arm and cast the curveball. They introduced a mid to high 80s slider/cutter hybrid pitch late in the season that he showed some promise with. He has worked on a changeup, but has not really used it in games. Estanista is definitely not a finished product, and is behind some of the other complex level breakout arms of the past like Adonis Medina or Franklyn Kilome were at the same point in their careers. That said, he has the fastball characteristics that those two arms did not, and knowing what we know now, that makes him very interesting. Ideally you would like to have this report attached to an 18 or 19 year old arm, but Estanista’s lack of experience makes his developmental path much like a young arm, because his struggles are due to development that has not yet happened as opposed to development that has failed. The Phillies will have every reason to keep Estanista in a rotation to build reps, and given his age and signing timeline, they may cause them to accelerate his level if he shows success in Clearwater. Given the current lack of a usable changeup, he has a high risk of being a reliever in the long term, but that is a conversation to revisit in a couple of years.
2023 Outlook: Estanista may be raw, but he is 21 and his Rule 5 clock is ticking. The Phillies may have to manage his innings, but they are going to need to start him with Clearwater and push him to Jersey Shore if his fastball allows him to manage Low-A.
