A key part to fielding a competitive team each season in dynasty fantasy baseball leagues, leagues like the ones here at dynastysportsempire.com, is to be very successful in finding the right prospects to fill your fantasy baseball roster and/or minor league system with. As your star and solid players age the time will come when their skills and production on the field diminish and you had better have a player waiting in the wings ready to become the consistent starter in place of that ageing veteran. If successful scouting and prospecting hasn’t been done then your dynasty league team surely will be headed into a longer than desired rebuild phase.
The purpose of this top 10 fantasy baseball dynasty league prospect series is to highlight the best prospects available in each MLB organization. Every prospect ranking system should have some sort of easy at-a-glance phrase that illustrates the expected MLB future fantasy baseball value of a prospect. I have opted to use the 5 star rating system.
5 STARS = Elite Future MLB Player. Decent or better chance of being a superstar fantasy baseball player. These are prospects that, barring injuries plaguing them, I expect to have a solid chance of having multiple MLB All-Star seasons. Many will become superstar players for a couple seasons. Some will become decade long MLB and fantasy baseball superstar players.
4 STARS = Great Future MLB Player. Decent or better chance of being an All-Star fantasy baseball player. These are prospects that I expect to have a solid chance of having at least one All-Star season at the MLB level. Many will have multiple All-Star seasons and be very valuable dynasty fantasy baseball players to have on your roster.
3 STARS = Good Future MLB Player. Decent or better chance of being a dependable fantasy baseball player. These are prospects I expect to have a solid chance of having many seasons as an everyday MLB player.
2 STARS = Common Future MLB Player. Decent or better chance of being a common fantasy baseball player. Prospect has enough known “tools” and/or “skills” to warrant some legitimate hope he will become a common or better everyday MLB level fantasy baseball player worthy of a roster spot. This is not a guarantee such a thing will happen as there is still much uncertainty with these prospects.
1 STAR = Maybe Common Future MLB Player. Marginal or better chance of being a common fantasy baseball player. Some will eventually become everyday MLB players as every season some prospects have breakout minor league seasons and become deserving of a higher prospect rating the following off-season. Often you will find many recent international signings listed here and many recent amateur draft picks as well.
0 STARS = Organizational Depth. Little chance of being a noteworthy fantasy baseball player.
Note: This is a snapshot in time. Prospects will continue to try to turn their “tools” into productive “skills.” They will make adjustments. Some will fade. Others will take that next step. I will do a short write-up on each player to give you a better overall impression of the prospect’s current and future value beyond his current rating. The statistics listed here are courtesy of fangraphs.com.
1 STAR PROSPECTS:
- Ronny Mauricio
Back in 2012 Amed Rosario was signed by the Mets for a $1.7 million bonus. Well, this past July the 16-year-old Mr. Mauricio signed for $2.1 million. We have a long ways to go before we know what Mr. Mauricio will eventually become, but I’m quite sure many Mets fans are rooting for another Rosario!
- Thomas Szapucki
SP, Age: 21, DOB: 6/12/1996
The Tommy John monster got to Mr. Szapucki, and it’s a shame, because he had a 2.79 ERA and 2.90 FIP (Fielding Independent Pitching) in 29 innings of work in A ball.
- Andres Gimenez
SS, Age: 19, DOB: 9/4/1998
Mr. Gimenez was an 18-year-old this season playing in A ball. That should not be lost in the analysis of him. He managed to hit .265 with a .310 BABIP (Batting Average on Balls In Play). His wRC+ of 107 indicates that he was a slightly above average prospect at the A ball level. This is impressive given his age. He also only struck out at a 15.3 percentage.
- Peter Alonso
1B, Age: 22, DOB: 12/7/1994
Mr. Alonso spent most of his time (346 plate appearances) in A+ ball and only 47 plate appearances in AA ball. Thus, due to the AA ball small sample size, we will look only at his A+ ball numbers. We have to be happy with the .286 batting average that went along with 16 home runs (.231 ISO) and an 18.5 K% (average…and I’m a tough grader on this one).
- Desmond Lindsay
OF, Age: 20, DOB: 1/15/1997
The positives: In 251 A ball plate appearances he had 8 home runs and a .168 ISO (Isolated Power). He also had a 13.1% walk percentage (great). The negatives: He only had a .220 batting average (with a normal .298 BABIP) and also had a 30.7 K% (beyond awful).
- David Peterson
OF, Age: 20, DOB: 1/15/1997
Mr. Peterson was the 20th overall pick of the 2017 June Amateur Draft. He only pitched 3.2 innings last season in A- ball, so there won’t be any statistical analysis for him.
- Marcos Molina
SP, Age: 22, DOB: 3/8/1995
In A+ ball Mr. Molina pitched 28.2 innings and posted a 1.26 ERA and 2.79 FIP. However, he spent most of his time in AA ball (78 innings pitched) and had a 3.92 ERA and 3.33 FIP while there. Hopefully in 2018 his K% increases and hopefully he can maintain his 6.4 walk percentage (above average).
- Adrian Hernandez
Mr. Hernandez was another 16-year-old international signing. Power and some speed seem to be his fantasy baseball assets at this point.
- Mark Vientos
3B, Age: 17, DOB: 12/11/1999
This young prospect was the 59th overall pick of the 2017 June Amateur Draft. He spent all of his time in Rookie ball this season where he hit 4 home runs in 193 plate appearances and had right around a .260 batting average.
- Justin Dunn
SP, Age: 22, DOB: 9/22/1995
This was not a good season for the 2016 June Amateur Draft 19th overall pick. It’s hard to get excited about a prospect that posts a 5.00 ERA and 4.15 FIP in 95.1 innings pitched in A+ ball. His K% wasn’t special and his BB% was beyond awful. This is a system weak on prospect talent, so he still makes the top 10 list. I always pull for prospects to make improvements and succeed and I hope that will be the case for Mr. Dunn in 2018.
