Each weekday during the minor-league season, FanGraphs is providing a status update on multiple rookie-eligible players. Note that Age denotes the relevant prospect’s baseball age (i.e. as of July 1st of the current year); Top-15, the prospect’s place on Marc Hulet’s preseason organizational list; and Top-100, that same prospect’s rank on Hulet’s overall top-100 list.

Summary
The former fifth-overall pick continues to struggle with his swing, leading to increasingly poor output as he climbs the ladder.

When the Rangers signed then-16-year-old Dominican Ronald Guzman in July 2011 for a whopping $3.45 million bonus, the 6’5″ hulk was said to profile as a corner outfielder with a big bat–the best offensive asset in the 2011 international amateur class. Over two years later, he remains a promising hitter–he hit .321/.374/.434 as a 17-year-old in the Rookie-level Arizona League and followed it up by posting a .272/.325/.387 line as an 18-year-old in Low-A this past campaign. He’s only gotten into 101 games due to a few injuries, but so far, Guzman’s offensive development is going about as well as the Texas front office probably hoped for. The other part of his profile, though, has changed.

Guzman was moved to first base almost immediately after signing. He has played in the outfield exactly once as a professional, back in 2012 for five innings to make room at first base for a then-rehabbing Mike Bianucci. To be fair, Guzman has played on teams that have featured notable outfield prospects like Nick Williams, Lewis Brinson, and Nomar Mazara, but his mooring to the game’s easiest defensive position at a young age owes far more to his lack of ability in the field than it does to his teammates. Guzman’s arm was widely panned as an amateur, he has a massive, sloping frame that doesn’t look built for speed (and will likely be even less so as he fills out), and he has a very odd gait that looks like he’s jogging on eggshells. Add it all up, and Guzman is, as WFAA’s Kate Morrison put it, “a first base prospect, not an outfielder/first baseman…but an honest-to-goodness stuck-at-first guy.”

In this post, I’m going to talk about the damnation of that designation.

A little over a month ago, I wrote this piece, examining how minor league catchers cut down on their passed ball rates over time. Indeed, anyone who peruses Baseball-Reference minor league catcher pages probably notices the tendency for teenage backstops to let pitches by them at alarming rates, only to ultimately settle into a more acceptable range as they reach their mid-twenties. On at least an anecdotal level, one can observe a similar phenomenon with left-side infielders–third base and shortstop are the most error-prone positions, and these tendencies can be blown up by inexperience. The worst qualified fielding percentage by an MLB shortstop in 2013 was Jed Lowrie‘s .962, and the worst from a qualified third baseman was Pablo Sandoval’s .940, but in, say, the Low-A South Atlantic League, ten of the fourteen third basemen who got over fifty games at the spot fell below that .940 fielding mark, and twelve of the fifteen shortstops didn’t break .962. And the short-season levels are a level of magnitude worse than that.

As with catchers, then, we can assume that left-side infielders cut down on their error totals significantly as time goes on. In this piece, I’m going to examine the development of shortstops in this area.

If you’re the sort of person who likes to look around minor league statistical leaderboards for under-the-radar performance prospects, the name Francisco Sosa may have emerged on your radar in 2013. Sosa’s 2013 statline has several intriguing numbers: his triple-slash was .315/.397/.529, he clubbed 20 homers and ripped 35 doubles, and he also swiped 30 bases. No other player in the minor leagues attained that combination of doubles, homers, and steals.

Sosa doesn’t really show up on prospect lists, though, for a few reasons. For one, he was a 23-year-old left fielder in Low-A, on the wrong side of the defensive spectrum and well older than most legitimate prospects who have yet to sniff the upper minors. Second, 2013 was the first time in his six-year career that he posted remotely interesting numbers–only twice before had he managed an on-base percentage over .310, and only once had he slugged over .400. Finally, he played in the silliest home park in organized baseball.

Like many minor league/prospect columnists, I try to see as much live baseball and as many minor league players as I can. Typically, I catch four or five games a week during the minor league season. It can be a bit of a grind at times, but I keep at it for two reasons: First, I want to be able to have the best and most far-reaching coverage I can, and second, because I’m usually having an awesome time doing it.

Of course, some games are more fun to attend from a scouting perspective than others. It’s a lot more exciting to take in the raw power of Joey Gallo, the blinding speed of Terrance Gore, the sweet swing of Francisco Lindor, or the arm strength of Eddie Butler than it is to watch 23-year-old Appalachian League middle relievers throw 84-mph fastballs to 23-year-old Appalachian League utility players. As such, I try to optimize my time and attend games that have the best likelihood of featuring interesting prospects, especially the starting pitchers. Typically, this decision is informed by some combination of the statistics, draft/prospect status, and reported tools/stuff of the players in question–in a way, I’m using a crude version of the same ideas behind our own Carson Cistulli’s NERD scores.

It’s a tremendous feeling to see a prospect in person and have them live up to what their statistics and reputation suggest they should look like. I heard all year about Atlanta’s Mauricio Cabrera and his triple-digit heat, so it was great to see him in person and watch a radar gun read “100” when I finally managed to catch one of his starts in August. Likewise, it’s disappointing to see a player underperform expectations. However, the most amazing experiences I have at games come when a player who’s way off the radar–uninteresting numbers and no scouting buzz–suddenly commands the most rapt attention. It doesn’t happen often, but it does happen, and today I want to share one of my experiences with the phenomenon and tie it in with some of our beliefs about the way players–in particular, relief pitchers–ascend to MLB relevance.

Just about anyone reading FanGraphs probably knows about the debate surrounding defensive statistics. About the only thing everyone seems to agree on is that all defensive statistics are inadequate reflections of defense, or at least need extremely large sample sizes to attain reliability. This is especially true with regard to catchers, whose defensive contributions are quite the riddle to solve.

These issues extend even more in the minor leagues, where the sole widely available statistics are the traditional ones–assists, putouts, errors, double plays, range factor, and fielding percentage. Needless to say, these are not broadly effective arbiters of defensive aptitude. Again, catcher defense is arguably even more elusive, with passed balls and caught-stealing percentage the only remotely notable metrics. The desperate search to link numbers to potential leads these stats to often stand for “receiving skills” and “throwing arm,” respectively, which is a gross overstatement of their utility.

In this post, I want to examine just how meaningful, or perhaps meaningless, the passed ball statistic is for catching prospects.

Austin Brice is a legitimate prospect. The Marlins spent $205,000 to sign him out of high school in 2010, and he was ranked as the sixteenth-best farmhand in the Miami organization by Baseball America coming into the 2013 season, an area of prospect lists he will likely to continue to reside in this offseason. He’s just 21, has two pitches that flash plus, and has a prototypical pitcher’s body and smooth, easy, delivery.

He also has 190 career walks in 279 2/3 professional innings, including 82 in 113 frames in 2013. That’s a career 14.88% walk rate and a 15.16% mark in 2013, a number that was actually a step back from 2012 (14.08%) even though he was repeating the Low-A level (his ERA also shot up from 4.35 to 5.73, and his K-rate fell from 25.26% to 20.52%. Certainly, this past season did not bring the young righthander much good news.

Plenty of pitching prospects pair tantalizing stuff with frustrating inabilities to throw strikes, but Brice (whom I saw five different times in 2013, a virtue of living 45 minutes from NewBridge Bank Park) is an especially frustrating case because, as I said above, his delivery is one of his strengths. In this piece, I’m going to examine the root of his control problems and tie it to some more general and important lessons about the process behind throwing strikes.

Quick: Who led minor league pitchers in FIP this year?* You might guess one of the top pitching prospects in baseball, such as Archie Bradley, Taijuan Walker, or Robert Stephenson. Or you might rack your brain thinking about 2013 breakout A-ball pitchers like C.J. Edwards, Tyler Glasnow, or Edwin Escobar. In either case, you’d be wrong, because the answer is little-known White Sox pitching prospect Tony Bucciferro.

*Minimum 80 IP. Giants relief prospect Derek Law had a lower FIP in 77 2/3, but I wanted to isolate starters.

Bucciferro’s 2013 numbers are certainly something to behold. Across three starts in the Rookie-Advanced Appalachian League and 13 outings (12 starts) in the Low-A South Atlantic League, he amassed 96 strikeouts, six walks, and a mere three homers allowed in 90 2/3 innings, good for a 1.74 FIP (2.48 ERA). Those numbers seem impossible to ignore, and yet Bucciferro registers barely a blip on the prospect radar. In this post, I will examine why he’s been successful, why he’s been ignored, and take a systematic look at how pitchers with this sort of statistical profile fare.
