It is hard enough to compile a list of breakout candidates in the preseason. Usually, these lists are pretty cookie-cutter and include a swath of young hitters supposed to be on the upswing. Gee, you’re predicting a young guy to get better and perhaps breakout? Throw enough darts at the youngins and some will turn out correct. But projecting a hitter to break out over the remaining 2 1/2 months of the season is even more difficult. How much should we weight the first 3 1/2 months versus the hitter’s career? Is the hitter hiding an injury if he has been a disappointment so far? Has age caught up to him? As usual, all we could do is analyze the various metrics we have at our disposal and make educated, higher percentage play guesses.

It is often said that closers are made, not born. Any experienced baseball fan knows this; it seems that for every Huston Street type who arrives with hype, four or five Jason Grillis, Andrew Baileys, or John Axfords slip into dominance after finding dead-ends in other roles. As such, predicting who will ascend to MLB closer roles (beyond the obvious “the best MLB non-closer relief pitchers”) is often a fool’s errand.

This becomes even more difficult when one attempts to find future closers in the minor leagues. Many of the pitchers who end up closing MLB games were starters all through their minor league careers, but it’s tough to project a minor league starter as a closer outright–in doing so, one is essentially saying “This pitcher will fail badly at the role he’s currently in and subsequently find tremendous success in a role he’s never pitched in.” Certainly plausible, but not something that seems like it can be said with much confidence. And minor league relievers–well, they’re equally problematic to forecast. After all, if a pitcher has a big future, why isn’t he able to crack a minor league rotation?

It’s certainly possible to envision any number of minor leaguers closing out ballgames–as so many sabermetricians are fond of saying, the role of garnering save totals can be accomplished reasonably effectively by any number of players, and the minor leagues have no shortage of interesting power pitchers that could fit a closer profile if things go their way. However, it’s quite another thing to actually predict that a minor league pitcher will end up amassing saves in the big leagues.

I think White Sox pitching prospect Daniel Webb merits such a prediction, though.

If you’ve ever had to go through a rebuilding phase with a dynasty league roster, you may have run against the difficulty of finding a minor league first baseman who projects as a bigtime MLB force. A couple of years ago, I discussed the extreme paucity of first base prospects here, and I feel that many of the points I raised in that piece still largely hold water. First base prospects are held to such a high standard of offense and are constantly competing with not only other first base prospects, but also defensively-challenged third base and corner outfield prospects, for the few open MLB spots at the position. Most of the first base prospects that do ascend to considerable MLB playing time–let alone success–at the spot are the players who are pegged as bigtime prospects from the moment they sign a professional contract–witness Prince Fielder, Mark Teixeira, Eric Hosmer, Adrian Gonzalez…even guys traditionally at the lesser end of the quality spectrum like Justin Smoak, Ike Davis, and James Loney.

If you’re in a dynasty league with any depth, chances are that most of the “obvious” first base prospects have been swept up (if you’re looking for a first baseman of the future and the big prospects aren’t swept up, stop reading this article and grab Jonathan Singleton). Who might you be able to turn to that’s a bit lower-profile (and thus available) but still could end up as a solid producer at the first base position? Today, I’m going to look at five players who might fill that void.

Last week, I examined unlikely minor league stolen base leader Micah Johnson, whose 58 swipes in the Low-A South Atlantic League have propelled him past some better-known base thieves (Billy Hamilton, Rico Noel, Byron Buxton, Roman Quinn, and Delino DeShields Jr., just to name a few) to a double-digit lead in the category. By now, Johnson–ranked among Chicago’s top 30 prospects by Baseball America entering the season and also sporting a hefty batting line–has started to gain publicity. It is less known, however, that the SAL also houses the current minor league home run leader: Hickory’s Ryan Rua, who has amassed 24 blasts, one ahead of highly-touted teammate Joey Gallo and well-traveled minor league slugger Mauro Gomez.

As with Johnson, Rua’s ascent to the top of the homer leaderboard was tough to foresee. He was a 17th-round pick in 2011 out of Division II Lake Erie College, where he had 27 homers in a three-year career. In 126 career professional games before 2013, all at short-season levels, he had just eleven homers. He had a very good .191 Isolated Power in rookie ball and a more pedestrian .136 in short-season-A play.

That lack of a track record, as well as Rua’s somewhat advanced age (he’s 23), may lead some to dismiss him as irrelevant for prospecting purposes, let alone fantasy ones, if not for one very important fact.

He plays second base.

At long (long, looong) last, the time has come.

Here are the top 20 fantasy rookies for the 2013 season, from Aaron Hicks to, well…why spoil the fun?

It might be odd to tout the virtues of a man who just allowed 7 earned runs in 3.2 innings during his 2013 debut against the Yankees on Tuesday. It is even stranger to gush about this very man given that he was just optioned to Triple-A. But if you hear me out, you will be convinced that this is a guy worth speculating on and stashing, especially in deep/AL-Only leagues and keepers.

I asked. You answered. Who knew the most commented on post with my byline would be a poll about OBP leagues? Over 1,000 of you play in leagues that count OBP in some way or another. So that means I will be publishing articles specifically focusing on players in this scoring format. Today I will identify a couple of hitters who may be available in your league and gain value when OBP, rather than AVG, is a category.

This probably should have been posted before the season, but the idea just came to me. We see research here all the time, and that research often produces fantasy baseball sleepers, so let’s gather them in one place.

We here at RotoGraphs preach patience. There is nothing worse than making a reactionary transaction based on a small performance sample and then a month later looking back and realizing your mistake. Unfortunately, every league has at least a couple of owners who simply cannot stop themselves from dropping the slow starter after a week and adding the flavor of the day. This means that your patient approach is going to almost guarantee you will miss out on the breakouts who went undrafted. So with that in mind, let’s look at the ultra tiny sample of one game to analyze some of the lesser owned hitters who launched a home run on opening day.

It’s time for the second annual Top 100 Fantasy Rookies, a list of 100 prospects who should make an impact on the 2013 fantasy baseball season. Just how much impact? In some cases, a lot; but in others, it may be minimal — or even negligible. That’s the inherent risk in predicting and projecting not only prospects’ development curves but also how these players possibly fit into their big league teams’ plans during the upcoming season.

That’s why, much like with my Mining the Minors columns, I’ve incorporated both talent and opportunity into each prospect’s ranking. Sometimes, a player’s talent is so elite that it’s worth bumping him up the rankings even if his path to playing time isn’t all that clear (think: Mike Trout last year). But there are also plenty of players in these rankings who skew toward the opportunity side of the spectrum, because they’re (nearly) ready to be in the majors on Opening Day (read: David Phelps, 2012). Trying to weigh and balance these two aspects — talent and opportunity — is what makes a list like this so challenging. And so fluid. Which is to say, my mind could change on any of the players on the list between today and tomorrow. Or even today and later today.

Here’s the fourth batch, from Brett Jackson to Bruce Rondon.

Nos. 100-81
Nos. 80-61
Nos. 60-41
