My top 100 prospects ranking from late January focused on long-term career value, which meant the list included many teenaged prospects who easily could be five years from producing any positive value for a major league team. If we're looking just at this upcoming season, however, the rankings are very different, and I've produced my ranking of the top 20 impact prospects for 2014.

After those 20, I've listed a number of other players who could come up this season and be above replacement-level if they get the chance.
I do not rank players with experience in a foreign major league as prospects, though those players are still officially considered rookies in MLB when they debut here.
If I included them on my rankings, Masahiro Tanaka and Jose Abreu would be 1-2 on this list; both are older, more experienced players than the kids ranked in this top 20, and I think both will have an immediate impact in the majors, making the AL Rookie of the Year competition this year extremely fierce.
With that said, here are my top 20 prospects based on the impact they will have in 2014.
1. Nick Castellanos, 3B | Detroit Tigers
Castellanos tops the list because he has a full-time gig waiting for him, little internal competition, and plenty of ability to make an impact in the near term. His defense might not be ready for prime time, but his glove already is a real improvement over the one he's replacing, and I think he's got rookie of the year potential if neither Tanaka nor Abreu runs away with it.
2. Xander Bogaerts, SS | Boston Red Sox
Bogaerts was my No. 2 overall prospect this winter and appears to have the shortstop job to himself unless the team brings back Stephen Drew. Bogaerts' game is more balanced than Castellanos', with more value on defense and better ability to get on base, but he's a little less physically mature than Castellanos and may have a longer growth period until he's an impact hitter.
3. Jackie Bradley Jr., CF | Boston Red Sox
Like Bogaerts, Bradley appears to have a job nailed down, and unlike Bogaerts there isn't a veteran free agent lurking out there to steal playing time for a year. Bradley's glove is ready now -- it was ready last spring -- but he was overmatched in April once pitchers started trying to get him out rather than just tuning up in early March (small sample size caveats apply). He's more prepared now, and should post a solid mid-.300s OBP with 8-10 homers and plus-plus defense.
4. Erik Johnson, RHP | Chicago White Sox
Maybe more a workhorse than a future ace, Johnson has made a ton of progress since the White Sox drafted him two years ago out of Cal, and he has a couple of potential out pitches in his arsenal, along with the build for 200-plus innings a year. He could easily be Chicago's third-most valuable starting pitcher in 2014.
5. Travis d'Arnaud, C | New York Mets
The archetypal GWH player -- Good When Healthy. D'Arnaud can catch, throw, and hit for power, but has to stay on the field. The Mets don't have a heavy-use backup on the 40-man, so they're counting on d'Arnaud to catch 120 games this year, which should mean 15-20 homers and excellent defense if he can stay out of the trainers' room.
6. Jake Marisnick, CF | Miami Marlins
In an ideal organization, Marisnick would have finished last year in the minors and would start 2014 in Triple-A, working on his approach and recognition of off-speed stuff before reaching the majors in the middle of this year. Instead, he's in the majors now, ready on defense, likely to hit 20-plus homers if he gets 500 at-bats, but also a fair bet to post a sub-.300 OBP if he can't make some quick adjustments.
7. Billy Hamilton, CF | Cincinnati Reds
The Reds are giving professional baseball's fastest man the center field job -- there's no proper backup on the roster, as Skip Schumaker can't handle center on more than an emergency basis -- and we're about to find out whether Hamilton can hit.
His total lack of power has become a problem, especially from the left side, as pitchers crowd him in to prevent him from slapping the ball the other way and beating out every ground ball. If he holds the job all year, he could still swipe 50-60 bases even with a low (think .300ish) OBP, and I think he'll save 10 runs a year on defense.
8. George Springer, OF, Houston Astros
Springer is the first player on my list who doesn't appear to have a full-time job already, but he could come up at any point in the first half of the season, and I think his impact will be immediate -- power, speed, along with good defense anywhere he plays. He'd be higher if he had the job from day one, but I don't think the Astros have any rational reason to do that when they can save his service time in a season in which they won't contend.
9. Kolten Wong, 2b | St. Louis Cardinals
What you saw last fall doesn't reflect Wong's skill set, between the small sample and the irregular playing time. He's the regular second basemen for the NL champs, and capable of posting a .280/.340/.380 line with neutral defense this year.
10. Matt Davidson, 3B | Chicago White Sox
Davidson has some competition for the regular third-base job, both in March or if he should scuffle in April/May, but he's the best option on their 40-man roster and a good bet to hit .250/.330/.425 or so if he gets regular playing time, with average or just below-average defense.
11. Taijuan Walker, RHP | Seattle Mariners
Walker and lefty James Paxton both have shots at breaking camp with the Mariners this April, with slight competition for the last two rotation spots. Walker has better stuff, with a possible swing-and-miss cutter, but a tendency to leave the fastball up because of his upright finish. I think he'll miss a lot of bats right out of the chute, but keeping the ball down and in the park will be key for him to be even league-average this year.
12. Oscar Taveras, RF | St. Louis Cardinals
Taveras likely would have been the Cardinals' starting right fielder on Opening Day had he not missed nearly all of 2013 with an ankle injury. He's expected to be 100 percent when he reports to spring training and I don't think Matt Adams and Allen Craig are long-term obstacles to Taveras' playing time. When Taveras, who reminds me a lot of Vlad Guerrero but from the left side, shows he's healthy and can rake against Triple-A pitching, he'll be in St. Louis, forcing Adams to part-time duty.
13. Marcus Semien, IF | Chicago White Sox
Semien could play any of three spots for Chicago -- short, second, or third -- or he could just play a lot of each of them as a true "super-utility" player, getting 400-450 at bats while spelling all three starters. Second baseman Gordon Beckham hasn't sniffed a .330 OBP or a .400 SLG since his rookie year, and he's a fringe defender at best. Semien could end up taking over that job by midseason and forcing a trade or non-tender of Beckham before 2015.
14. Chris Owings, SS | Arizona Diamondbacks
One of Arizona's best moves this offseason was a non-move, keeping both Owings and shortstop Didi Gregorius and allowing the surplus to play itself out before rushing to trade one of the two players. Gregorius is the incumbent but was a non-factor at the plate after his first 10 games in the majors. Owings is almost as good a defender, but has far better bat speed and gap power. He should be the starter coming out of spring training, with Gregorius heading to Triple-A to try to shorten up his swing and improve his approach against southpaws.
15. Kevin Gausman, RHP | Baltimore Orioles
Gausman was filthy in relief at the end of 2013, but he's still a starter in my eyes and in Baltimore's as well, a horse with a chance for three plus pitches if the slider we saw in September can come with him to a starting role this year. If you're looking for a guy in the 11-20 range on this list who, by year-end, will clearly have belonged in the top five, this is the best bet. He's a volatile asset but with huge upside if that slider clicks.
16. Jake Odorizzi, RHP | Tampa Bay Rays
Jeremy Hellickson's injury pushes Odorizzi, a very similar pitcher, into the team's Opening Day rotation, where he'll get lots of help from his team's stellar defense and should be above replacement-level, thanks to his ability to throw four pitches for strikes. I don't think he'll miss enough bats to be average, but could end up getting 30 or so starts for Tampa Bay, which doesn't have a lot of rotation depth heading into this season.
17. Marcus Stroman, RHP | Toronto Blue Jays
Stroman could help the Jays in two ways this year, even if he doesn't make the team out of spring training. He might be one of the five best starting options in the organization today -- the Jays' main choices after their front three are guys coming off injuries (such as J.A. Happ and Drew Hutchison) and pitchers who have proven they're not major league starters (such as Esmil Rogers).
But Stroman also would be lights-out in a relief role, and not limited to 10-15 pitch outings, which might matter because no one the Jays have in the bullpen behind Casey Janssen is any kind of lock. One way or another, Stroman should spend most of the year with the big league club.
18. Josmil Pinto, C | Minnesota Twins
Pinto is probably the heir apparent to Joe Mauer in Minnesota. His bat is ready to play, but his glove isn't, and he'll likely always be an offense-first catcher. The Twins will face a tough decision this year on how to work Pinto into the major league lineup; he needs to catch every day to improve his receiving -- and he'd probably be better off doing that in Triple-A -- but he's also their best candidate to give them some offense behind the plate.
19. Archie Bradley, RHP | Arizona Diamondbacks
The Snakes just handed their fifth starter's job -- and an enormous pile of money -- to Bronson Arroyo, which fills their rotation on paper for now and leaves Bradley waiting for an injury or other opportunity to make his major league debut. That'll come at some point this year, likely in June or so.
His stuff is ready, but his command isn't, although the latter has been improving the past two years. Even if he only gets 15-18 starts in the majors in 2014, he'll be among the NL's best rookie starters.
20. Jameson Taillon, RHP | Pittsburgh Pirates
Like Bradley, Taillon is more poised to be an impact call-up than a full-season big leaguer in 2014. And like Bradley, Taillon has better present stuff than he does command. Bradley has the better overall package of pitches and feel, but Taillon has just as much velocity and he will get a lot of chases on his slider, at least from right-handed hitters.
His system-mate, Nick Kingham, is more polished and could also get an early call-up, but Taillon brings bigger upside for the long term and I'd bet he gets the first shot when there's an opportunity.
