Power Prospect Standouts By Age

Projection is a term thrown around heavily within prospect writing and scouting reports. More often than not, projection is discussed in terms of physical growth and the budding development of game power. Projecting power is an essential part of the job for those covering prospects for public consumption, and of course for those paid to scout and analyze players for major league organizations.
Power projection falls into a series of buckets.
- Players with present strength and raw power, who struggle to consistently elevate.
- Players further away from their maximum power capacity due to being physically immature.
- Players with a consistent ability to elevate but lack average or better raw power.
With access to minor league statcast data, we have the ability to correctly identify which bucket a prospect’s power projection falls into. With data dating back to 2019, we’ve been able to study the progression of power as a player ages.
From ages 17 to 23 on, average players progress rapidly when it comes to raw power. We use 90th percentile exit velocity as a measure for raw power because it looks at the top 10% of a player’s batted balls and draws an average. It correlates with isolated slugging well, and when it comes to developing major league hopefuls, it gives us a measuring stick against major league hitters.
Below is the average 90th percentile by age from 17 to 23.
Age | 90%EV |
17 | 96.5 |
18 | 98.1 |
19 | 99.1 |
20 | 100 |
21 | 101.3 |
22 | 101.5 |
23 | 102.1 |
You can see from ages 17 to 21 there is consistently a jump on 1 mph or greater from year to year. This is the period where the most power development happens. The largest jump is between 19 and 21, where hitters add more than 2 mph on average onto their 90th percentile exit velocity.
Now that we have a better understanding of how power develops on a scale, let’s look at the 90th percentile leaders for each age group between 17 and 21. There’s a minimum in-zone contact rate minimum filter of 20% to eliminate power hitters struggling to consistently get into power.
All players included below have a minimum of 150 plate appearances.
Age 17 Leaders – 96.5 mph 90th Percentile Exit Velocity average.
PLAYER | ORG | 90%EV |
Robert Calaz | COL | 107.2 |
Sebastian Walcott | TEX | 106.4 |
Angel Guzman | SF | 102.7 |
Luis Merejo | CLE | 102.1 |
Alfredo Alcantara | CIN | 101.9 |
Ethan Salas | SD | 101.8 |
Elias Medina | LAD | 101.6 |
Alfonzo Martinez | TB | 101.4 |
Mario Baez | ATL | 100.9 |
Yophery Rodriguez | MIL | 100.7 |
- When laid out on against their age-based peers, it’s clear to see how outlier both Robert Calaz and Sebastian Walcott’s power is. This group features almost exclusively 2023 international signees.
- It’s likely that the sample size is boosting Calaz and Walcott. Each had around 200 plate appearances, and it’s likely in over 400-500 plate appearances those numbers would come down, but likely only a few mph.
- Standout performers Ethan Salas and Yophery Rodriguez make the leaderboard showing they have above-average present raw power, hitting at more slugging ability to come.
Age 18 Leaders – 98.1 mph 90th Percentile Exit Velocity average.
PLAYER | ORG | 90%EV |
Cam Collier | CIN | 105.6 |
Waner Luciano | HOU | 104 |
Echedry Vargas | TEX | 103.9 |
Jeral Perez | LAD | 103.7 |
Jesus Baez | NYM | 103.5 |
Josue Briceno | DET | 103.3 |
Jose Rodriguez | MIN | 103.1 |
Jancel Villarroel | HOU | 102.8 |
Ricardo Cabrera | CIN | 102.6 |
Randy De Jesus | LAA | 102.6 |
- Cam Collier sticks out for not only his well above-average 90th percentile exit velocity, but he’s also the only 18-year-old in this sample with over 250 plate appearances. Collier averaged 105.6 mph on his top 10% of contact over a whopping 462 at-bats. Despite excellent EV data, Collier’s expected production falls short due to his struggles to elevate.
- Waner Luciano and Echedry Vargas are both strong performers from the domestic complex leagues this year, who should get an opportunity to show off their above-average raw power for their age in 2024 when they debut in full season. Both Luciano and Vargas have shown the ability to elevate on hard contact.
Age 19 Leaders – 99.1 mph 90th Percentile Exit Velocity average.
PLAYER | ORG | 90%EV |
Jeffry Rosa | NYM | 105.9 |
Luke Adams | MIL | 105.9 |
Jackson Chourio | MIL | 105.8 |
Roman Anthony | BOS | 105.3 |
Moises Ballesteros | CHC | 104.9 |
Sal Stewart | CIN | 103.3 |
Justin Crawford | PHI | 103.1 |
Rayne Doncon | LAD | 102.8 |
Anderson De Los Santos | BAL | 102.8 |
- This showcases a few of the top prospects in the game. Jackson Chourio has shown prodigious power since he debuted stateside, and the underlying exit velocity data backs that. Not only does Chourio hit the ball much harder than the average 19-year-old, but he also shows an uncanny ability to elevate on his best contact.
- Luke Adams continues to be one of the more underrated hitters in the minors based on the data. If you can get over the aesthetics of his swing, you’ll see he has a a strong combination of average bat-to-ball skills, strong approach and plus raw power.
- Justin Crawford’s inclusion might come as a surprise, but hitting the ball hard isn’t an issue. Elevating on hard contact very much is a problem. Crawford falls into the grouping of hitters that have present strength but struggle to get the ball in the air.
Age 20 Leaders – 100 mph 90th Percentile Exit Velocity average.
PLAYER | ORG | 90%EV |
Junior Caminero | TB | 110.4 |
Ryan Clifford | HOU | 107.1 |
Jasson Dominguez | NYY | 105.7 |
Jeferson Quero | MIL | 105.2 |
Marcelo Mayer | BOS | 105.1 |
Blaze Jordan | BOS | 104.1 |
Derwin Laya | SF | 103.9 |
Won-Bin Cho | STL | 103.7 |
Hedbert Perez | MIL | 103.6 |
- This should put Junior Caminero’s power into perspective. Of all the players included within these age-based leaderboards Caminero is the only player to average 110 mph or higher on his top 10% of batted balls. With above-average bat-to-ball skills, Caminero combines outlier power with the ability to get to it.
- Some of the more notable power hitters in the minors show up on the age-20 list. Ryan Clifford, Jasson Dominguez, Marcelo Mayer and Blaze Jordan are all well-known players with potential for plus power or better at peak.
- Jeferson Quero’s inclusion might surprise some, but the Brewers catching prospect packs a punch. He’s a strong contact hitter with plus raw power. It’s simply a matter of refining his, at times, overzealous approach to get to his already burgeoning power.
Age 21 Leaders – 101.3 mph 90th Percentile Exit Velocity average.
PLAYER | ORG | 90%EV |
Tyler Soderstrom | OAK | 107.6 |
Coby Mayo | BAL | 107.2 |
Joe Vetrano | LAD | 106.8 |
Matt Shaw | CHC | 106.8 |
Noelvi Marte | CIN | 106.8 |
Wyatt Langford | TEX | 106.8 |
Yohendrick Pinango | CHC | 106.6 |
Orelvis Martinez | TOR | 105.4 |
Chase DeLauter | CLE | 104.7 |
Colson Montgomery | CWS | 104.7 |
- When we get to age 21, the cream begins to rise to the top. There are eight Top 100 Prospects included in the age-21 leaderboard. Only Joe Vetrano and Yohendrick Pinango rank outside the top prospects in the game.
- This should be reason for optimism with Tyler Soderstrom, who’s seen his prospect status falter in recent years. He still shows potential for plus-plus power. It’s simply a matter of refining his plates skills, which is easier said than done.
- Matt Shaw and Wyatt Langford skyrocketed to the top of these leaderboards post-draft. The one asterisk is their total plate appearance number, which was lower than the others included in this list.
