The National High School Invitational starts on Wednesday, and with it, 16 of the top high school teams in the country will descend on the USA Baseball National Training Complex in Cary, N.C. As usual, the rosters in this tournament are deep with talent.
As the 2017 high school season has gotten underway, the landscape of prep talent for the 2017 Draft has changed. There's still a bit more than two months until the June 12-14 event, so it's likely to change a lot more, but below is look at the Top 25 high school players in this year's Draft class. Seven of them will be participating in the NHSI this week.
• Elite prospects pack 2017 NHSI
* NHSI participant
1. Hunter Greene, RHP/SS, Notre Dame High, Sherman Oaks, Calif.
Greene could become the first high school right-hander to go No. 1 overall, and he is talented enough to be a first-round pick as an infielder as well. His plus stuff combined with his athleticism plays very well on the mound.
2. Royce Lewis, SS/OF, JSerra Catholic High, San Juan Capistrano, Calif.
Playing shortstop for his high school team, the super-athletic Lewis has also shown the ability to play center field, which many consider his future home. He started slow, but he's starting to pick it up now.
* 3. Nick Pratto, 1B/LHP, Huntington Beach (Calif.) High
A two-way player who has separated himself with the bat this spring, Pratto has long been a favorite of area scouts, but he's now getting more national attention as he's added power to his advanced feel to hit.
4. Jordon Adell, OF/RHP, Ballard High, Louisville, Ky.
Adell is just getting started, and he homered early. The tools are plentiful, it's just a question of whether he can use them consistently.
5. D.L. Hall, LHP, Valdosta (Ga.) High
Hall has thrown well in the early stages, picking up where he left off with his three-pitch mix, remaining a priority for national scouts everywhere.
6. Trevor Rogers, LHP, Carlsbad (N.M.) High
Rogers really put himself on the map with a strong showing over the summer. While his stuff has backed up a little bit early this spring, there is a ton of projection to this 6-foot-6 left-hander.
* 7. Jacob Heatherly, LHP, Cullman (Ala.) High
A year ago, Braxton Garrett came to the NHSI with his Alabama high school team and threw very well. He eventually went No. 7 overall in the Draft. Heatherly, with his durable body and his feel for pitching, could follow a very similar path.
* 8. Hans Crouse, RHP, Dana Hills High, Dana Point, Calif.
Crouse has wiped away a rough first start against Garrett Mitchell and having to skip a start with a minor wrist issue. Since then, he's been back to his normal sense, touching the mid-90s with a good breaking ball, though some scouts still see a reliever profile.
9. Austin Beck, OF, North Davidson High, Arcadia, N.C.
Beck was off of radars because a knee injury kept him off the summer showcase circuit, but he was showing off multiple tools as the spring unfolded, with power, speed and center-field skills intriguing scouts.
10. Blayne Enlow, RHP, St. Amant (La.) High
While Enlow's velocity has been down a bit compared with his summer showcase performance, he has still shown a very good delivery and command of three pitches, perhaps overusing his outstanding breaking ball.
11. MacKenzie Gore, LHP, Whiteville (N.C.) High
Gore's stock continues to rise as he throws well this spring, showing off his athleticism and pitchability, not to mention his outstanding changeup. He and Beck might fight it out for first high school product taken from North Carolina.
12. Calvin Mitchell, OF, Rancho Bernardo High, San Diego
Mitchell is all about the bat and has garnered Garret Anderson comps in the past. He's gotten off to a bit of a slow start, but the potential to be a run-producing corner outfielder will have scouts coming to see him all spring.
13. Quentin Holmes, OF, Monsignor McClancy Memorial High, East Elmhurst, N.Y.
Living in the Northeast, Holmes hasn't really gotten his season going just yet. But scouts will be pouring into New York to see how his top-of-the-scale speed looks as the Draft approaches.
14. Nick Allen, SS, Francis Parker School, San Diego
Everyone loves Allen's defense, speed and makeup, but his size (or lack thereof) makes him very hard to place on Draft boards. He has added some strength this spring, which might help some teams feel more comfortable with taking him early.
15. Alex Scherff, RHP, Colleyville (Texas) Heritage High
While Scherff's stock was down a little early this spring, he has enough of a track record, especially over the summer, to keep scouts coming to see if his plus fastball, excellent changeup and breaking ball look like they did on the showcase circuit.
16. Drew Waters, OF, Etowah High, Woodstock, Ga.
Georgia has always been good for high school talent, especially outfielders, and Waters is the next in line. He's carried over a strong summer showcase showing off tools at the plate, on the basepaths and in center field.
17. MJ Melendez, C, Westminster Christian School, Palmetto Bay, Fla.
Melendez likes to show off his catch-and-throw skills, but there's been more questions about the bat. He's made some strides physically; it remains to be seen how it will translate.
18. Shane Baz, RHP, Concordia Lutheran High, Tomball, Texas
Early reports on the Texas right-hander have been good this spring. The TCU commit has four pitches in his arsenal, led by his fastball and cutter.
19. Jeremiah Estrada, RHP, Palm Desert (Calif.) High
Estrada has been as consistent as usual, up to 94 mph, with good secondary offerings. Teams will have to get over his undersized right-hander stature to take him early.
* 20. Garrett Mitchell, OF, Orange (Calif.) Lutheran High
Mitchell is chock full of tools, especially speed, though he hasn't shown much power yet this spring. The industry seems to still be concerned about his Type 1 diabetes.
* 21. Alex Toral, 1B, Archbishop McCarthy High, Southwest Ranches, Fla.
Toral has been a name for quite some time, with the power potential to profile at first base. He's gotten off to a slow start this spring, though there's time for him to get his bat going.
22. Cole Brannen, OF, The Westfield School, Perry, Ga.
Brannen may have finished the summer as the top Georgia prep outfielder, but it seems like Waters has passed by him. But he still has plus speed, excellent bat speed and the skills to play center field.
23. Kyle Hurt, RHP, Torrey Pines High, San Diego
Hurt had a knee issue over the fall and rushed back this spring to face Calvin Mitchell a bit too quickly, but when 100 percent, he has an intriguing three-pitch mix coming from a strong and projectable frame.
* 24. Mark Vientos, SS/3B, American Heritage School, Plantation, Fla.
Vientos will almost certainly need to move to third at the next level. He'll be big and physical as he fills out his 6-foot-4 frame, but he'll have to make more consistent contact to tap into his raw power.
* 25. Brady McConnell, SS, Merritt Island (Fla.) High
McConnell started last summer looking like one of the top high school players in the country. He hasn't kept that up, but he still has tools as an up-the-middle infielder.
