We outlined the Top 25 rookies to target on Draft Day and Fantasy Baseball's Top 100 prospects, so now we split them off with the Top NL prospects for those in NL-only leagues.

These prospects might not necessarily make the team out of camp, but they will be some of the most-hyped minor leaguers throughout the season. They are ranked for their potential long-term rewards in Fantasy leagues.

There are 100's of others that can get call-ups and help Fantasy owners in the near future, too, so go through our Organizational Prospect Reports we did last fall to get an even deeper view of all the teams' top farmhands.

CBSSports.com's Top NL-only prospects
RK Player POS TM AGE 2009 high 2010 start
1 Jason Heyward OF ATL 20 Triple-A Majors
We see now why everyone is going with Heyward at No. 1 and we're jumping on board with gusto.
2 Stephen Strasburg SP WAS 21 NCAA Double-A
Without throwing an official pro pitch, the best pitching prospect ever and slipped to the No. 2 spot.
3 Michael Stanton OF FLA 20 Double-A Double-A
It will be real interesting to watch which NL East RF prospect winds up with the most power in seven years.
4 Pedro Alvarez 3B PIT 23 Double-A Triple-A
Masher has some questions about his weight and position, but there's no question about the bat.
5 Buster Posey C SF 23 Majors Triple-A
Joe Mauer, Matt Wieters and Posey figure to battle for the No. 1 Fantasy status in a few short years.
6 Madison Bumgarner SP SF 20 Majors Majors
He gets far less pub, but he is just eight days older than the ballyhooed Braves outfielder Heyward.
7 Aroldis Chapman SP CIN 22 Defecting High Class A
If he is as good as the hype suggests, the Reds have the making of some dominant rotation long term.
8 Alcides Escobar SS MIL 23 Majors Majors
We would rank him higher if the power was a bit better. As it, this a pretty significant spot to be ranked.
9 Logan Morrison 1B FLA 22 Double-A Triple-A
We are not quite sure how much power will come, but we will trust the scouts and BP shows at this point.
10 Domonic Brown OF PHI 22 Double-A Triple-A
With Raul Ibanez's age and injury history and Jayson Werth's pending free agency, Brown could arrive in '10.
11 Starlin Castro SS CHC 20 Double-A Double-A
The Cubs are pushing him hard this spring, begging the question of whether he could actually arrive in '10.
12 Christian Friedrich SP COL 22 High Class A Double-A
He will be a real intriguing candidate for a June 1 call-up if the Rockies decide they need a starter in-season.
13 Jason Castro C HOU 22 Double-A Triple-A
We like the Baseball America comparison that called him the next A.J. Pierzynski this winter.
14 Tyler Matzek SP COL 19 High school Low Class A
We haven't seen him as a pro yet, but Baseball America says he is the next Cole Hamels with better stuff.
15 Ike Davis 1B NYM 22 Double-A Triple-A
A promising spring could put him in the mix to arrive in the middle of 2010 and become an immediate mainstay.
16 Fernando Martinez OF NYM 21 Majors Triple-A
Years of injury woes have tarnished his prospect status, but all that presumed potential has to still be there.
17 Derek Norris C WAS 21 High Class A Double-A
Spending this spring alongside Ivan Rodriguez should help Norris immensely, but he will remain in minors all year.
18 Jarrod Parker SP ARI 21 Double-A Double-A
Tommy John surgery has ruined most of his 2010 season, but he still remains one of the best long-term projects.
19 Yonder Alonso 1B CIN 22 Double-A Triple-A
With Joey Votto not set at first, the Reds are looking to find a new position for Alonso this spring; he can hit, though.
20 Freddie Freeman 1B ATL 20 Double-A Double-A
He was a bit disappointing last season, but he remains the Braves' long-term option at first base, perhaps in late '10.
21 Todd Frazier OF CIN 24 Triple-A Triple-A
The Reds are considering this converted shortstop in left, second or perhaps third base; he should hit anywhere.
22 Donovan Tate OF SD 19 High school Low Class A
The Padres selected the Georgia product at No. 3 overall last June and was able to lure him away from football.
23 Timothy Alderson SP PIT 21 Double-A Triple-A
His stock slipped last year, because of declining velocity, so watch him closely this season for another fall.
24 Jonathon Niese SP NYM 23 Majors Majors
His stuff isn't electric, but he changes speeds and knows how to pitch despite his inexperience and young age.
25 David Freese 3B STL 26 Triple-A Majors
He is currently atop the Cards depth chart and could be a huge 27-year-old breakout this year.
26 Chris Heisey OF CIN 25 Triple-A Majors
We consider him an Eric Byrnes type and he could earn a starting job in left for the Reds.
27 Josh Vitters 3B CHC 20 High Class A High Class A
The Cubs kept him out of trades thus far, so he still could be Aramis Ramirez's replacement in a few years.
28 Phillippe Aumont SP PHI 21 Double-A Double-A
His move to the bullpen was supposed to speed up his arrival, but he is back to starting and likely a '10 arrival.
29 Ian Desmond SS WAS 24 Majors Triple-A
He was going to get a shot at starting this spring, but he likely won't arrival to June 1 or midseason now.
30 Jaff Decker OF SD 20 Low Class A High Class A
A Jason Kubel type outfielder who likely won't be a factor this year, but he could position himself for 2011.
31 James Darnell 3B SD 23 High Class A Double-A
The South Carolina product can position himself for an in-season with a hot start; he might switch positions.
32 Aaron Poreda SP SD 23 Majors Triple-A
There is talk he might need to move to the bullpen, but the Padres have plenty of time to invest in him.
33 Logan Forsythe 3B SD 23 Double-A Triple-A
We compared him to a Mark Teahen-type and now he might give second a try like Teahen did last year.
34 Drew Storen RP WAS 22 Double-A Triple-A
If he wasn't a reliever, we would rank him a lot higher. We will regret it when he becomes the Nats' closer.
35 Chris Marrero 1B WAS 21 Double-A Double-A
Future masher hasn't displayed the type of power many expected thus far, but he is still real, real young.
36 Gaby Sanchez 1B FLA 26 Majors Majors
We rank Morrison higher due to potential, but Sanchez is more likely to open at 1B for the Marlins.
37 Jenrry Mejia SP NYM 20 Double-A Double-A
Wicked stuff has the Mets thinking he might be able to pitch out of the bullpen in the majors this year.
38 Shelby Miller SP STL 20 Low Class A Low Class A
Baseball America says the Cardinals haven't had a pitching prospect this good since Rick Ankiel. Interesting.
39 Jaime Garcia SP STL 23 Triple-A Triple-A
Tommy John surgery stalled his expected arrival in 2008, but he is healthy now and could be their No. 5 starter.
40 Lance Lynn SP STL 22 Triple-A Triple-A
The Cards' 2008 first-rounder had a great season in Double-A and could be another potential impact call-up.
41 Wilmer Flores SS NYM 18 Low Class A Low Class A
Those Miguel Cabrera comparisons look like a stretch, but there are still a lot of years for him to grow.
42 Christopher Withrow SP LAD 21 Double-A Double-A
The 2007 first-rounder out of a Texas high school handled Double-A as a 20-year-old quite impressively.
43 Matt Dominguez 3B FLA 20 Double-A Double-A
A subpar 2009 campaign was a bit surprising for Moustakas' high school teammate; he could turn it back around.
44 Mike Minor SP ATL 22 Low Class A High Class A
The Vandy first-round pick has drawn comparisons to Jeremy Sowers, who is more command than power.
45 Dee Gordon SS LAD 21 Low Class A High Class A
Burner could make himself a candidate to replace Rafael Furcal as early as the beginning of 2011.
46 Julio Teheran SP ATL 19 Low Class A High Class A
This power-armed Colombian is a potential No. 1 pitching prospect candidate in a few more years.
47 Brett Lawrie 2B MIL 20 Double-A Double-A
Usually a move from catcher hurts a prospects value, but Lawrie could arrive in the majors quicker now.
Best of the rest
